The Mac

The Macintosh (pronounced /ˈmækɨntɒʃ/ MAK-in-tosh),[1] or Mac, is a series of several lines of personal computers designed, developed, and marketed by Apple Inc. The first Macintosh was introduced on January 24, 1984; it was the first commercially successful personal computer to feature a mouse and a graphical user interface rather than a command-line interface.[2] The company continued to have success through the second half of the 1980s, only to see it dissipate in the 1990s as the personal computer market shifted toward the "Wintel" platform: IBM PC compatible machines running MS-DOS and Microsoft Windows.[3]
Years later, Apple consolidated its multiple consumer-level desktop models into the 1998 iMac all-in-one. This proved to be a sales success and saw the Macintosh brand revitalized, albeit not to the market share level it once had. Current Mac systems are mainly targeted at the home, education, and creative professional markets. They are: the descendants of the original iMac and the entry-level Mac mini desktop models, the Mac Pro tower graphics workstation, the MacBook, MacBook Air and MacBook Pro laptops. The Xserve server will be discontinued in early 2011.[4]
Production of the Mac is based on a vertical integration model in that Apple facilitates all aspects of its hardware and creates its own operating system that is pre-installed on all Mac computers. This is in contrast to most IBM PC compatibles, where multiple sellers create and integrate hardware intended to run another company's operating software. Apple exclusively produces Mac hardware, choosing internal systems, designs, and prices. Apple does use third party components, however, such as graphics subsystems from nVidia and ATi. Current Mac CPUs use Intel's x86 architecture; the earliest models (1984–1994) used Motorola's 68k and models from 1994–2006 used the AIM alliance's PowerPC. Apple also develops the operating system for the Mac, currently Mac OS X version 10.6 "Snow Leopard". The modern Mac, like other personal computers, is capable of running alternative operating systems such as Linux, FreeBSD, and, in the case of Intel-based Macs, Microsoft Windows. However, Apple does not license Mac OS X for use on non-Apple computers.1979 to 1984: Development

The Macintosh project started in the late 1970s with Jef Raskin, an Apple employee, who envisioned an easy-to-use, low-cost computer for the average consumer. He wanted to name the computer after his favorite type of apple, the McIntosh,[5] but the name had to be changed for legal reasons as it was too close, phonetically, to that of the McIntosh audio equipment manufacturer. Steve Jobs requested a release of the name so that Apple could use it, but was denied, forcing Apple to eventually buy the rights to use the name.[6] Raskin was authorized to start hiring for the project in September 1979,[7] and he began to look for an engineer who could put together a prototype. Bill Atkinson, a member of Apple's Lisa team (which was developing a similar but higher-end computer), introduced him to Burrell Smith, a service technician who had been hired earlier that year. Over the years, Raskin assembled a large development team that designed and built the original Macintosh hardware and software; besides Raskin, Atkinson and Smith, the team included George Crow,[8] Chris Espinosa, Joanna Hoffman, Bruce Horn, Susan Kare, Andy Hertzfeld, Guy Kawasaki, Daniel Kottke,[9] and Jerry Manock.[10][11]
Smith’s first Macintosh board was built to Raskin’s design specifications: it had 64 kilobytes (KB) of RAM, used the Motorola 6809E microprocessor, and was capable of supporting a 256×256 pixel black-and-white bitmap display. Bud Tribble, a Macintosh programmer, was interested in running the Lisa’s graphical programs on the Macintosh, and asked Smith whether he could incorporate the Lisa’s Motorola 68000 microprocessor into the Mac while still keeping the production cost down. By December 1980, Smith had succeeded in designing a board that not only used the 68000, but increased its speed from 5 MHz to 8 MHz; this board also had the capacity to support a 384×256 pixel display. Smith’s design used fewer RAM chips than the Lisa, which made production of the board significantly more cost-efficient. The final Mac design was self-contained and had the complete QuickDraw picture language and interpreter in 64 KB of ROM – far more than most other computers; it had 128 KB of RAM, in the form of sixteen 64 kilobit (Kb) RAM chips soldered to the logicboard. Though there were no memory slots, its RAM was expandable to 512 KB by means of soldering sixteen IC sockets to accept 256 Kb RAM chips in place of the factory-installed chips. The final product's screen was a 9-inch, 512x342 pixel monochrome display, exceeding the prototypes.[12]


The original 1984 Mac OS desktop featured a radically new graphical user interface. Users communicated with the computer not through abstract textual commands but rather using a metaphorical desktop that included icons of real life items with which the user was already familiar.
The design caught the attention of Steve Jobs, co-founder of Apple. Realizing that the Macintosh was more marketable than the Lisa, he began to focus his attention on the project. Raskin finally left the Macintosh project in 1981 over a personality conflict with Jobs, and team member Andy Hertzfeld said that the final Macintosh design is closer to Jobs' ideas than Raskin's.[7] After hearing of the pioneering GUI technology being developed at Xerox PARC, Jobs had negotiated a visit to see the Xerox Alto computer and Smalltalk development tools in exchange for Apple stock options. The Lisa and Macintosh user interfaces were partially influenced by technology seen at Xerox PARC and were combined with the Macintosh group's own ideas.[13] Jobs also commissioned industrial designer Hartmut Esslinger to work on the Macintosh line, resulting in the "Snow White" design language; although it came too late for the earliest Macs, it was implemented in most other mid- to late-1980s Apple computers.[14] However, Jobs’ leadership at the Macintosh project did not last; after an internal power struggle with new CEO John Sculley, Jobs resigned from Apple in 1985,[15] went on to found NeXT, another computer company,[16] and did not return until 1997 when Apple acquired NeXT.The Macintosh 128K was announced to the press in October 1983, followed by an 18-page brochure included with various magazines in December.[18] The Macintosh was introduced by the now famous US$1.5 million Ridley Scott television commercial, "1984".[19] The commercial most notably aired during the third quarter of Super Bowl XVIII on 22 January 1984 and is now considered a "watershed event"[20] and a "masterpiece."[21] "1984" used an unnamed heroine to represent the coming of the Macintosh (indicated by a Picasso-style picture of Apple’s Macintosh computer on her white tank top) as a means of saving humanity from the "conformity" of IBM's attempts to dominate the computer industry. The ad alludes to George Orwell's novel, Nineteen Eighty-Four, which described a dystopian future ruled by a televised "Big Brother."[22][23]
Two days after the 1984 ad aired, the Macintosh went on sale. It came bundled with two applications designed to show off its interface: MacWrite and MacPaint. It was first demonstrated by Steve Jobs in the first of his famous Mac Keynote speeches, and though the Mac garnered an immediate, enthusiastic following, some labeled it a mere "toy."[24] Because the operating system was designed largely around the GUI, existing text-mode and command-driven applications had to be redesigned and the programming code rewritten. This was a time consuming task that many software developers chose not to undertake, and could be regarded as a reason for an initial lack of software for the new system. In April 1984 Microsoft's MultiPlan migrated over from MS-DOS, with Microsoft Word following in January 1985.[25] In 1985, Lotus Software introduced Lotus Jazz for the Macintosh platform after the success of Lotus 1-2-3 for the IBM PC, although it was largely a flop.[26] Apple introduced Macintosh Office the same year with the lemmings ad. Infamous for insulting its own potential customers, the ad was not successful.[27]


The Apple Macintosh Plus at the Design Museum in Gothenburg, Sweden.
For a special post-election edition of Newsweek in November 1984, Apple spent more than US$2.5 million to buy all 39 of the advertising pages in the issue. Apple also ran a “Test Drive a Macintosh” promotion, in which potential buyers with a credit card could take home a Macintosh for 24 hours and return it to a dealer afterwards. While 200,000 people participated, dealers disliked the promotion, the supply of computers was insufficient for demand, and many were returned in such a bad shape that they could no longer be sold. This marketing campaign caused CEO John Sculley to raise the price from US$1,995 to US$2,495 (adjusting for inflation, about $5,200 in 2010).In 1985, the combination of the Mac, Apple’s LaserWriter printer, and Mac-specific software like Boston Software’s MacPublisher and Aldus PageMaker enabled users to design, preview, and print page layouts complete with text and graphics—an activity to become known as desktop publishing. Initially, desktop publishing was unique to the Macintosh, but eventually became available for other platforms as well.[30] Later, applications such as Macromedia FreeHand, QuarkXPress, Adobe Photoshop, and Adobe Illustrator strengthened the Mac’s position as a graphics computer and helped to expand the emerging desktop publishing market.
The limitations of the first Mac soon became clear: it had very little memory, even compared with other personal computers in 1984, and could not be expanded easily; and it lacked a hard disk drive or the means to attach one easily. Many small companies sprang up to address the memory issue, by upgrading the 128K Mac to 512 KB, by removing the computer's 16 memory chips and replacing them with larger-capacity chips, a tedious operation that was not always successful. In October 1985, Apple increased the Mac’s memory to 512 KB,[31] and offered an upgrade for 128K Macs that involved replacing the logic board. In an attempt to improve connectivity, Apple released the Macintosh Plus on January 10, 1986 for US$2,600. It offered one megabyte of RAM, easily expandable to four by the use of socketed RAM boards, and a SCSI parallel interface, allowing up to seven peripherals—such as hard drives and scanners—to be attached to the machine. Its floppy drive was increased to an 800 KB capacity. The Mac Plus was an immediate success and remained in production, unchanged, until October 15, 1990; on sale for just over four years and ten months, it was the longest-lived Macintosh in Apple's history.[32]


The Macintosh II, one of the first expandable Macintosh models.
Updated Motorola CPUs made a faster machine possible, and in 1987 Apple took advantage of the new Motorola technology and introduced the Macintosh II, which used a 16 MHz Motorola 68020 processor.[33] The primary improvement in the Macintosh II was Color QuickDraw in ROM, a color version of the graphics language which was the heart of the machine. Among the many innovations in Color QuickDraw were an ability to handle any display size, any color depth, and multiple monitors.
The Macintosh II marked the start of a new direction for the Macintosh, as now for the first time it had an open architecture with several NuBus expansion slots, support for color graphics and external monitors, and a modular design similar to that of the IBM PC. It had an internal hard drive and a power supply with a fan, which was initially fairly loud.[34] One third-party developer sold a device to regulate fan speed based on a heat sensor, but it voided the warranty.[35] Later Macintosh computers had quieter power supplies and hard drives.
In September 1986 Apple introduced the Macintosh Programmer's Workshop, or MPW that allowed software developers to create software for Macintosh on Macintosh, rather than cross compiling from a Lisa. In August 1987 Apple unveiled HyperCard, and introduced MultiFinder, which added cooperative multitasking to the Macintosh. Apple began bundling both with every Macintosh.
The Macintosh SE was released at the same time as the Macintosh II, as the first compact Mac with a 20 MB internal hard drive and one expansion slot.[36] The SE's expansion slot was located inside the case along with the CRT, potentially exposing an upgrader to high voltage. For this reason Apple recommended users bring their SE to an authorized Apple dealer to have upgrades performed.[37] The SE also updated Jerry Manock and Terry Oyama's original design and shared the Macintosh II's Snow White design language, as well as the new Apple Desktop Bus (ADB) mouse and keyboard that had first appeared on the Apple IIGS some months earlier.
In 1987, Apple spun off its software business as Claris. It was given the code and rights to several applications that had been written within Apple, notably MacWrite, MacPaint, and MacProject. In the late 1980s, Claris released a number of revamped software titles; the result was the “Pro” series, including MacPaint Pro, MacDraw Pro, MacWrite Pro, and FileMaker Pro. To provide a complete office suite, Claris purchased the rights to the Informix Wingz spreadsheet on the Mac, renaming it Claris Resolve, and added the new presentation software Claris Impact. By the early 1990s, Claris applications were shipping with the majority of consumer-level Macintoshes and were extremely popular. In 1991, Claris released ClarisWorks, which soon became their second best-selling application. When Claris was reincorporated back into Apple in 1998, ClarisWorks was renamed AppleWorks beginning with version 5.0.[38]


The Macintosh Portable was Apple's first battery-powered Macintosh. It was available from 1989 to 1991 and could run System 6 and System 7.
In 1988, Apple sued Microsoft and Hewlett-Packard on the grounds that they infringed Apple’s copyrighted GUI, citing (among other things) the use of rectangular, overlapping, and resizable windows. After four years, the case was decided against Apple, as were later appeals. Apple’s actions were criticized by some in the software community, including the Free Software Foundation (FSF), who felt Apple was trying to monopolize on GUIs in general, and boycotted GNU software for the Macintosh platform for seven years.[39][40]
With the new Motorola 68030 processor came the Macintosh IIx in 1988, which had benefited from internal improvements, including an on-board MMU.[41] It was followed in 1989 by a more compact version with fewer slots (the Macintosh IIcx)[42] and a version of the Mac SE powered by the 16 MHz 68030, the Macintosh SE/30.[43] Later that year, the Macintosh IIci, running at 25 MHz, was the first Mac to be “32-bit clean,” allowing it to natively support more than 8 MB of RAM,[44] unlike its predecessors, which had “32-bit dirty” ROMs (8 of the 32 bits available for addressing were used for OS-level flags). System 7 was the first Macintosh operating system to support 32-bit addressing.[45] Apple also introduced the Macintosh Portable, a 16 MHz 68000 machine with an active matrix flat panel display that was backlit on some models.[46] The following year the Macintosh IIfx, starting at US$9,900, was unveiled. Apart from its fast 40 MHz 68030 processor, it had significant internal architectural improvements, including faster memory and two Apple II CPUs dedicated to I/O processing.

iPad 2 rumors????


It’s nearly impossible to keep up with the chatter surrounding the iPad 2. Every day it seems like there’s a new rumor about a new model, a new launch date or even a USB port. It’s a bit overwhelming.
That’s why we decided to scour the web for the most prominent iPad 2 rumors and create a comprehensive guide detailing what we think is likely to be in the next generation of the iPad.
We’ve picked out our top 10 rumors and provided not only our analysis, but the percentage chance a specific iPad 2 rumor will actually come to fruition. We’d bet money on some of these rumors (two cameras), while others will only happen when pigs learn how to fly (the mythical 7-inch iPad).
Without further ado, here is our comprehensive guide to the iPad 2 rumors:

Rumor #1: There Will Be Three Versions of the iPad 2






One of the biggest rumors sweeping the web recently is that there will be three version of the iPad 2. One will be Wi-Fi only, one will support Wi-Fi and UMTS, the 3G technology utilized by AT&T Mobility, and the third model will support Wi-Fi and CDMA, used by Verizon Wireless for its 3G network. In other words, there will be a Verizon iPad.
According to DigiTimes, Apple will be shipping the Wi-Fi, UMTS and CDMA iPad 2 models in a 3:4:3 ratio, specifically because nearly two out of three of current iPad shipments are 3G models. There are currently two models of the iPad, a Wi-Fi version and a Wi-Fi + UMTS version that works exclusively on the AT&T network in the U.S.
This rumor makes total sense: Apple wants to expand the reach of the iPad, and adding a CDMA model for Verizon would complement a Verizon iPhone perfectly. Recently, Verizon started selling the Wi-Fi iPad with the Verizon MiFi 2200. We’re sure Verizon would much rather sell a CDMA iPad instead.
Likelihood of Happening: 85%

Rumor #2: iPad 2 Will Have a Front and Back-Facing Camera

Ever since the iPhone 4 was released, there have been multiple reports claiming that the new iPad will finally come with a front and a back-facing camera.
The primary reason cited for the change from the original iPad is Facetime. In order for Facetime to succeed as a product, Apple needs to flood the market with as many Facetime-capable devices as possible.
We expect Apple to rectify its biggest omission from the original iPad with the next generation model.
Likelihood of Happening: 99%

Rumor #3: Slimmer, Lighter and Retina Display

Earlier this month, reuters was told by its sources that the new iPad would be slimmer and lighter than its predecessor and would have a “better resolution display than the first iPad.”
Well, duh. Apple always tries to make its products slimmer and lighter. Just look at the iPhone’s evolution or the new MacBook Air for proof. It’s also a no-brainer that the iPad 2 will support Retina Display.
Likelihood of Happening: 99%

Rumor #4: The iPad 2 Will Have a Flat Back





This week there has been buzz about the 2nd generation iPad sporting a flat back after a supposed third party case was leaked to the web.
There’s no way that case is real, and you can take that to the bank. Why? Because Apple never releases the specs for new products to third party accessory makers; they’ve been burned too many times by leaks from third parties to make that type of rookie mistake.
This was completely apparent with the launch of the iPhone 4. There were no third party cases available at launch because none of the manufacturers knew the dimensions of the device. So trust us when we say the supposedly leaked iPad 2 case is total crap.
With that said, we wouldn’t be surprised if Apple did decide to make the back of the device flat. It makes more sense ergonomically. Still, the new iPod touch has a curved back, so it’s anybody’s guess what Apple plans to do.
Likelihood of Happening: 40%

Rumor #5: iPad 2: Now With Wide-Range Speakers?






Another rumor, this one from a Japanese blog, claims that the iPad 2 will not only have a thinner bezel, but that it will have a wide-range speaker covered with a metal mesh that will have far greater speaker capabilities.
This rumor kind of makes sense, given that there’s a greater need for the device to project sound. The iPad is a family device, and in order for a family to enjoy a movie together on the iPad, it needs to have decent speakers. We expect an upgraded speaker.
Still, we agree with Engadgett: the source has no track record and should be taken with a grain of salt. It won’t look like Mac Otakara’s CG render.
Likelihood of Happening: 50%

Rumor #6: The iPad 2 Will Have a USB Port

This rumor, courtesy of the Chinese publication Economic Daily News, claims Apple’s new tablet will have a USB port so it can connect to other devices. This would be a huge development because it would allow for the easy movement of files and information from USB drives and peripherals like printers or mice.
Unlike some of the other rumor sources on this list, Economic Daily News has a good track record. As PC World points out, it was the first one to figure out that Apple was building a tablet, not a netbook. DigiTimeshas also reported that the next generation iPad will sport a USB port.
Frankly, we’re not sure how much truth there is to this one, but it could happen. We just wouldn’t put our money on it.
Likelihood of Happening: 33%

Rumor #7: The iPad 2 Will Have a Dual-Core CPU






An analyst for Rodman & Renshaw made a stir just before Christmas by saying that the next generation iPad and iPhone will utilize a dual-core processor powered by two 1GHz ARM Cortex A9 cores.
A dual-core processor would give the iPad 2 and iPhone 5 far greater multitasking capabilities and would be a significant development in mobile technology.
The iPad 2 wouldn’t be the first mobile device to utilize a dual-core, though. That honor goes to the LG Optimus 2X Android smartphone. Do you really think Apple’s going to let Android beat them? No way.
Likelihood of Happening: 75%

Rumor #8: Non-Smudge Screen & Gyroscope

We won’t dive into these rumors too much, but suffice it to say, a screen that smudges less and an iPad that supports gyroscope functionality and apps just makes sense.
Likelihood of Happening: 90%

Rumor #9: A 7-Inch Version of the iPad?

We’ve heard multiple rumors claiming that Apple is not only building a 9.7-inch version of the iPad 2, but it’s also making a smaller, 7-inch model. The thinking is that a smaller model would be cheaper and more useful in certain situations.
Well, forget it. In an epic rant during Apple’s most recent earnings call, Steve Jobs himself shot down the possibility of a 7-inch iPad. The reason, he said, was that there simply wasn’t enough screen real estate for creating great tablet apps.
“While one could increase the resolution of the display to make up for some of the difference, it is meaningless unless your tablet also includes sandpaper, so that the user can sand down their fingers to around one quarter of their present size,” Jobs said during the earnings call.
In other words, the 7-inch iPad isn’t happening.
Likelihood of Happening: 2%

The Big Question: When Will the iPad 2 Launch?

Cameras, Facetime, a new speaker and a dual-core processor are all great potential additions to the iPad, but what we really want to know is when we will have one of the next generation iPads in our hands.
Nobody can seem to agree when it will launch. We’ve heard that the new iPads are coming in January (exactly a year after the original iPad’s launch), but we’ve also heard March and April.
The release date of the iPad likely depends on the launch date of the Verizon iPhone. Apple is unlikely to launch the iPad 2 and the Verizon iPhone at the same event, so if the Verizon iPhone comes out in March, we expect the iPad 2 in January, and if the Verizon iPhone arrives in January, then don’t expect the iPad 2 until March.
If we had to venture a guess, we’d say the new iPad will come out of the shadows in March, but it’s likely Apple hasn’t set the launch date for the next generation of its tablet, so it could come at almost any time.

iPad

The iPad is a tablet computer designed, developed and marketed by Apple primarily as a platform for audio-visual media including books, periodicals, movies, music, games, and web content. At about 1.5 pounds (680 grams), its size and weight fall between those of contemporary smartphones and Apple computers. Apple released the iPad in April 2010, and sold 3 million of the devices in 80 days.
According to a report released by Strategy Analytics, the Apple iPad had gained a 95 percent share of Tablet PC sales at the end of second quarter 2010. During the second quarter 2010, Apple had sold 4.19 million iPads around the world.
The iPad runs the same operating system as the iPod Touch and iPhone—and can run its own applications as well as iPhone applications. Without modification, it will only run programs approved by Apple and distributed via its online store.
Like iPhone and iPod Touch, the iPad is controlled by a multitouch display—a departure from most previous tablet computers, which used a pressure-triggered stylus—as well as a virtual onscreen keyboard in lieu of a physical keyboard. The iPad uses a WI-FI data connection to browse the Internet, load and stream media, and install software. Some models also have a 3G wireless data connection which can connect to HSPA data networks. The device is managed and synced by iTunes on a personal computer via USB cable.
Media reaction to the device has generally been neutral or positive, with more positive reaction after the device was launched.

Apple's first tablet computer was the Newton Messagepad 100, introduced in 1993, which led to the creation of the ARM6 processor core with Acorn Computers. Apple also developed a prototype PowerBook Duo-based tablet, the Pen Lite, but in order to avoid hurting MessagePad sales did not sell it. Apple released several more Newton-based PDAs, and discontinued the last, the MessagePad 2100, in 1998.
With the success of the introduction of portable music player iPod in 2001, Apple re-entered the mobile-computing market in 2007 with the iPhone. Smaller than the iPad but featuring a camera and mobile phone, it pioneered the multitouch finger-sensitive touchscreen interface of Apple's mobile operating system—iOS. By late 2009, the iPad's release had been rumored for several years. Mostly referred to as "Apple's tablet", iTablet and iSlate were among the speculated names. The iPad was announced on January 27, 2010, by Steve Jobs at an Apple press conference at the Yerba Buena Center For The Arts in San Francisco.
Jobs later admitted that development started on the iPad before the iPhone. Upon realizing that it would work just as well as a mobile phone, Jobs put development of the iPad on hold and decided to develop the iPhone instead.
The iPad's touchsreen display is a 9.7 in (25 cm) liquid crystal display (1024 × 768 pixels) with finger-print resistant and scratch-resistant glass. Steve Jobs backed the choice of screen size, saying a 7-inch screen would be "too small to express the software." He said 10 inches was the minimum for a tablet screen. Like the iPhone, the iPad is designed to be controlled by bare fingers; normal gloves and styli that prevent electrical conductivity may not be used, although there are special gloves and capacitive styli designed for this use.
The display responds to two other sensors: an ambient light sensor to adjust screen brightness and a 3-axis accelerometer to sense iPad orientation and switch between portrait and landscape modes. Unlike the iPhone and iPod touch built-in applications, which work in three orientations (portrait, landscape-left and landscape-right), the iPad built-in applications support screen rotation in all four orientations (the three aforementioned ones along with upside-down), meaning that the device has no intrinsic "native" orientation; only the relative position of the home button changes.
In total there are four physical switches on the iPad, including a home button below the display that returns the user to the main menu, and three plastic physical switches on the sides:wake/sleep and volume up/down, plus a third which, as of iOS 4.2, acts as a mute switch. Initially this switch was utilized to lock out the screen rotation function (reportedly to prevent unintended rotation when the user is lying down). However, with the iOS 4.2 update, this functionality was removed and rotation lock is now controlled with a software toggle via the iOS task switcher. There is no means to reassign the physical switches functionality in the official iOS release.
