Well, I'm off to college and I'm excited about getting a MBP. In my city, it's pretty customary for parents to buy HS seniors laptops when they go off to college. My parents have agreed to follow suit. I might be going with an education discount, so yeah..nice to keep in mind. So before, resolution has always been a pressing issue for me. Before the refresh, the 15" has had a resolution far too small for me. But now...I think with the $150 upgrade to hi-res antiglare, resolution is workable now. Portability isn't really necessary, I won't be lugging it EVERYWHERE so portability is not an issue. The only difference is the 15" has i7 and the 17" has i5. Expresscard vs sd won't matter for me. So the 15" with hi-res antiglare will bring me to 2350 (rounded up from 2349). The 17" with antiglare will bring me up to 2350 as well. Only differences: size, resolution (17" is still larger..), and i7 vs i5. I'm not sure how big of a difference the 15" i7's 2.66ghz will be compared to the 17" i5's 2.53ghz.
