MacBook Air - The World's Thinnest Notebook

The new MacBook Air isn't actually invisible like I first suspected. Nor does it float. It's just way thin and has no optical drive. The Air rocks a 13.3" screen, is 0.76 inches at the thickest, weighs 3 pounds, and features a multi-touch trackpad. It comes with an ultrathin 80GB hard drive, but you've got the option for a 64GB solid-state drive if you prefer yours with no moving parts. Part of the Air's appeal is its incredible wireless diversity. You can install software on the machine by "borrowing" the disk drive of another computer and having it send the data to the Air.

You can also transfer files wirelessly from another computer or the new Time Capsule external HD/Wi-Fi station. The 1.6GHz with 80GB standard hard drive starts at $1,800. The 1.8GHz with 64GB solid-state hard drive starts at $3,100. Both models begin shipping in two weeks.
