The Macintosh , or Mac, is a series of several lines of personal computers designed, developed, and marketed by Apple Inc.

History

The announcement of the iMac in 1998 was a source of discussion and anticipation among commentators, Mac fans, and detractors. Opinions were divided over Apple's drastic changes to the Macintosh hardware. At the time, Apple was trying to improve its retail strategy. Apple declared that "the back of our computer looks better than the front of anyone else's".

Apple declared the 'i' in iMac to stand for "Internet

Updates

In 2005, as it became more and more apparent that IBM's development for the desktop implementation of PowerPC was grinding to a halt, Apple announced that it would be switching the Macintosh to the x86 architecture and Intel's line of Core processors. The first Intel-equipped Macs were unveiled on January 10, 2006: the Intel iMac and the introductory MacBook Pro. Within nine months, Apple had smoothly transitioned the entire Macintosh line to Intel. One of the highly touted side benefits of this switch was the ability to run Windows on Mac hardware.

On July 27, 2010, Apple updated its line of iMacs to feature the new Intel Core processors across the line. The 21.5" models, including the high end 27", now feature the Core i3 processor, but these are upgradable to the Core i5. The high end 27" features a Quad-Core i5 processor, which is upgradable to a Quad-Core i7. On this date Apple also announced its new "Apple Magic Trackpad" peripheral, a trackpad similar to that of the MacBook Pro for use with the iMac, or any other Apple computer. They also introduced their first ever AA NiMH battery charger intended to simplify the use of batteries in its new peripherals. Apple offers an option to use a solid state hard drive instead of a large mechanical drive.

On May 3, 2011, Apple updated its iMac line with the introduction of Intel Thunderbolt technology and Intel Core i5 and i7 Sandy Bridge

. This came at a price, however. As USB was far slower than a number of ports available at the time such as SCSI, unmodified iMacs and iBooks were badly crippled until adequate replacements such as FireWire and USB 2.0 became standard. After the iMac, Apple continued to remove older peripheral interfaces and floppy drives from the rest of its product line.

Apple's focus on design has allowed each of its subsequent products to create a distinctive identity. Apple avoided using the beige colors then pervading the PC industry.

Apple is facing a class-action lawsuit for allegedly deceiving the public by promising millions of colors from the LCD screens of all Mac models while its 20 inch model only held 262,144 colors. This issue arose due to the use of 6-bit per pixel Twisted nematic LCD screens, instead of higher quality technologies.

While not a criticism of the iMac per se, the iMac's integrated design has some inherent tradeoffs that have garnered criticism. In The Mythical Midrange Mac Minitower, Dan Frakes of Macworld suggests that with the iMac occupying the midrange of Apple's product line, Apple has little to offer consumers who want some ability to expand or upgrade their computers, but don't need (or can't afford) the Mac Pro

 upgrades, with the exception of those for the original iMac G3's "mezzanine" PCI slot. Models after the iMac G5 (excluding the August 7, 2007 iMac update) made it difficult for the end-user to replace the hard disk or optical drive, and Apple's warranty explicitly forbids upgrading the socketed CPU. While conceding the possibility of a minitower cannibalizing sales from the Mac Pro, Frakes argues there is enough frustration with iMac's limitations to make such a proposition worthwhile. This disparity has become more pronounced after the G4 era since the bottom-end Power Mac G5 (with one brief exception) and Mac Pro models have all been priced in the $1999–$2499 range, while base model Power Macs G4s and earlier were $1299–$1799.
