I finally decided to replace my 2007 (yes, 2007!) c2d 17" MBP with a 13" MBA - truth be told I spend more time on my 27" iMac and would prefer a slightly smaller laptop for travel (although I'm still one of the few that doesn't mind lugging a 17" MBP around!) Anyway, I was just about to pull the trigger but then these 15" MBA rumors re-surfaced, and if I'm honest, the thought of a 15" Air sounds like the perfect dream ultrabook combo to me. So, is anyone else actually holding out until there's something concrete about the 15" Air? And if so, do you think that the 15" Air will offer a higher resolution than the 13" Air (Considering the 13" already matches the standard MBP 15" resolution).
