According to Apple, this iMac’s slightly thinner, tapered case conceals numerous component changes that go way beyond simple improvements to processors and video cards. The iMac is the first Mac to use PCI Express, a growing connection technology in the PC world that’s faster than the AGP technology previously used to connect a Mac to its video cards. It’s also the first Mac to support DDR2 SDRAM, a faster RAM technology. The screen is brighter than the previous iMac models.
Then there’s the built-in iSight camera, its included remote control, and the new Front Row and Photo Booth programs, all of which are currently available only on the iMac.
