I have yet to mess with the MBA at the store, but it looks from photos and such that it isn't that thin. It seems like it is almost thicker because it sits up off the table but I wanna see it in real life anyway. I think Apple is just having trouble out doing themselves- I mean the MB and MBP are already an inch thick and that is pretty good. Just seems like when compared to these already very thin computers the MBA isn't as exciting or shocking.
