I have a last gen 15" MBP (2.2, 2gig ram) and was wondering if you guys think it's a good idea to sell my current laptop and get the 1599 MacBook? The things I like about the new Macbook is that it's smaller than my MBP and has decent enough graphics to play the games I play (CS:Source and other Source engine games). So with that said would you guys do it (I probably will end up spending a couple hundred more for this)?
