So is this the name of Apple's new subnotebook? Of course, we won't know for sure until Steve says it on stage, but while it's not, on the surface, Apple's best naming choice, it could work, in an "Airport" and "Air Tunes" kind of way. It could be worse-- the thing could be called the MacPod. Or the PodBook. Or the PodMac. Or the Lisa.
Update: macbookair.com isn't owned by Apple, but by some merry prankster. Let the speculation continue!
