I'm traveling for the first time with my MBA and it's interesting to see so many travelers, mainly business travelers, hauling out their large PC laptops. Compared to the Air, those computers look like dinosaurs. I don't mean this to sound smug, but as I'm traveling, I realize how practical the 11" Air is for these types of situations. I'm having no problem taking it in out of my travel bag or using it on the plane. The only thing I long for is that it had 3G connection.*
