I poured red wine over my trusty 2010 15 inch mbp i5 2.54 ghz last night so I'm forced to buy a new Mac. So after a few hours reading benchmarks online, I decided to buy a mba i7 with 8 gig of ram. Called the apple number and ordered but the sales person tried to convince me that I'm making a mistake; it would be a downgrade because the air only has a dual core. She advised me to buy the rmbp 15 inch instead as the maxed out mba is only a few hundred cheaper than the 15 mbp. However with the specs bump just round the corner, it doesn't seem like a good idea. So should I get the mba? Would it be slower than my current mbp?
