I sat in on a MacBook Air presentation at the Apple Theater today. A couple of interesting things, in case you missed it. The MacBook Air doesn't have an optical drive, but you can buy a special external USB SuperDrive to connect to it. But you don't need that if you have a fast wireless network. MacBook Air has a special feature that enables it to detect any other optical drives on the local wireless network. Other computers' optical drives show up in the sidebar under "Devices." If you want to install an application that's on an install DVD, put the DVD in a computer, and it shows up on the MacBook Air, as if the optical drive and the disc were part of the MacBook Air. How about using the Migration Assistant to transfer files to your new MacBook Air? Same thing. Mac Book Air's Migration Assistant works wirelessly on your wireless network.
