So I'm looking for a new laptop for high school (I have a pc now, which won't turn on, it's pretty much bricked) and I'm looking at the mba 13 inch. I have to buy this thing myself so I'm looking into the cheaper end of macs. So, I'd like to have a computer soon since it's hard fighting my family for our dell desktop (and I hate windows). So, would you say buy now (I can get $90 off on amazon.com right now) or wait until the new model comes out (I heard only better battery and Ivy Bridge). Battery doesn't matter much to me, and the current generation is plenty fast for me, though graphics could use a boost (The only game I play is GTA). In past generations apple has alternated between summer and autumn for air upgrades, and since last year was summer, it looks like an october upgrade this year, meaning I'll need to go through the first two months of school without a dedicated computer (my school strongly reccomends carrying a laptop), and that means the upgrade is almost half a year away. Any advice? Thanks!
