Integrated graphics processors that use a portion of main memory for video memory are no longer featured in any of the iMacs.

The iMacs also come standard with Wi-Fi, Bluetooth, built-in speakers, and a built-in iSight camera.Д«esides the processors, the graphics cards are the other major change with the new iMacs. ThereвЂ™s a headphone/optical digital audio output minijack, an audio line in/optical digital audio input minijack, four USB 2.0 ports, one FireWire 800 port, a Mini DisplayPort (with video-in support), and a Gigabit Ethernet port. The external ports havenвЂ™t changed from the previous generation of iMacs. You can also add AppleвЂ™s new Magic Trackpad ( ) for $69. All four iMacs have 8X SuperDrives, and right next to the SuperDrive slot is a SD card slot, which has been upgraded to support SDXC, a new format that allows for SD card capacity over 32GB.ДЄpple includes its Wireless Keyboard ( ) and the Magic Mouse ( ) with the iMac, but if you order online from the Apple Store, you can switch the keyboard to a wired version with a numeric keypad and switch the mouse to an Apple Mouse ( ), both for no extra fee. The iMacs use 7200-rpm hard drives the $1199 iMac has a 500GB drive, while the other three models have 1TB hard drives. The fourth iMac, a $1999 27-inch model, sports a 2.8GHz Core i5 quad-core processor with 8MB of level 3 cache. The $1199 21.5-inch iMac has a 3.06GHz Core i3, while the $1499 21.5-inch iMac and the $1699 27-inch iMac both feature 3.2GHz Core i3 processors. Apple now uses dual-core Intel Core i3 processors with 4MB of Level 3 cache in three of the new iMacs. The Intel Core 2 Duo processors found in the lower-end iMacs of the previous generation are gone. And though the four new iMacs (two 21.5-inch models and two 27-inch models) released in July provide only small speed boosts, these latest desktops will make most customers very happy. While the Mac business is a more mature product line than AppleвЂ™s mobile device lineup, it remains an important segment-both to Apple and the customers who use the Mac. But the Mac isnвЂ™t entirely out of the picture. ThereвЂ™s little doubt that 2010 is the year of the iPad and iPhone for Apple, with the company largely focusing on the new kids on the block.
