I currently have a Macbook (Late 2006) Core 2 Duo and I'm wanting to upgrade to a new Macbook Pro. I ultimately want the high-end 15" as I feel the specs would allow for a longer lifespan until my next upgrade. The 13" would do just fine for the moment but I'd prefer longevity plus I'd like to delve into more advance things like movie or music making down the road. I also would rather the anti-glare screen over the glossy. However given that Apple products generally have a high resale value I was thinking of getting a 13" now and then next summer when the new ones come out I'd do a trade-up to a much better 15". What do you guys think?
