As I wrote previously, MacBook Air (hereafter MBA) is in almost all aspect a more powerful system than a PowerBook G4 (from 2002), which I'm currently using as my only computer at work. At my desk I can plug the MBA into my 23-inch widescreen display (1920x1280 resolution is supported), and connect the keyboard and mouse through an usb hub. (Or through Bluetooth.) And who really nowadays uses cds or dvds for transferring files? Usb sticks are the way to go.

The only dissappointing thing about the MBA is the reported battery performance. If it is only 2.5 hours, this is far too little. (Although it is the same as with the PowerBook G4, but here I can switch batteries on the go.) If the battery would last four hours, that would be enough, and about six hours would be excellent. Perhaps the next revision can do this?
