I got the Core i7 MBP a couple months ago mainly because paid half the price in gift cards. The only thing negative i can say is does it ever run hot, even when i'm doing nothing more than surfing or watching a podcast, and when the fan comes on.... it sounds like a jet engine starting up. there are a few post of heating issues and im not sure if this affect Core i5 but it might be something to consider. By comparison, my old C2D stays cool in any situation or environment.
