I can't believe a company with Apple's savvy would pick a name as obtuse as MacBook Air. I'd bank on them using a slightly more hip sounding name like the MacBook Aero.
It's been said before and I'll say it again, MacBook Air is just stupid. There's NO WAY Apple would ever release a computer and call it that. Seriously, think about it.. Apple isn't going to use Air to describe its lightweight when it could just as easily use mini or nano. It's been said before and I'll say it again. Just quit it with the 'MacBook Air' it's just such a bad name there's no way it could be real.
My guest is that if a MacBook is gona be called "Air", it won't have the Ethernet connector and be only wireless... We've seen before patents trying to find solution to the problem of the height of the ethernet connector (which can be to high for a slim notebook)
