In the latest iMac line, released in August, consists of two 20-inch models and the $2,400, 24-inch model. The previous model's white plastic design has been replaced with a glass screen surrounded by anodized aluminum and black plastic trim. There is a downside with redesign: The tiny iMac remote, which can be used to control music and video playback, can no longer be magnetically attached to the side of the screen—making it easier to misplace or lose when not in use.
As we know, setting up the iMac is mostly a trouble-free affair. For several users, it's as easy as plugging in the power cable, the mouse, and a redesigned, wafer-thin keyboard.
