My significant other has gotten bit by the Macbook bug She really wants a MBA, so I think I'm going to try and find her one for Christmas. Being students, money is a bit tight. I've found a couple of MBA's in the range of $600-$800US. 600 being a MBA 1,1 and 800ish being either a MBA 2,1-3,1. Aside from the obvious hardware, is there a HUGE difference (real life performance) between a MBA 1,1 and a MBA 3,1 given semi-equal hardware ratings? She won't be using it for anything more than MS Office and browsing the net. No photo-editing, music, or anything resource-heavy. I'm just afraid that after using my White macbook 2,1 and then my MBP 7,1 she'll think that the MBA is a toy (performance-wise). Any suggestions and insight will be greatly appreciated.
