So im trying to figure out which 15" MacBook Pro I should buy and thought I would get your guys thoughts on it. Here is what I am looking for. I want a everyday computer, that will travel with me. I will not be doing anything graphic intensive or video editing. Its a computer that I hope to keep for a few years as my main computer. Here is my thoughts on the two. The 2.4 is attractive because of the price - $1299 The 2.53 is nice because of the built in battery and being able to upgrade to 8 gigs instead of just 4 with the 2.4. The 2.53 is $1449. I just am unsure and would like some thoughts. Thanks alot everyone.
