Hands on with the new thin 2012 iMac

Take a look at Apple's new all-in-one computer.

Face front

Look directly at the new iMac, and you can’t tell the difference from the previous model. In this picture, the older 21.5-inch iMac is to the left, and the new 21.5-inch iMac is to the right.

Macworld Lab has two new iMacs; both are “ultimate” configurations with build-to-order options for faster processors, more memory, and Fusion Drives. We have a complete set of benchmark results.

The new iMacs are now available for purchase.
