I'm looking to buy a macbook pro 13" sometime soon for my first year of college so that i can take advantage of the free touch and printer rebate. I have never owned a mac before so this is all somewhat new to me. I plan on using it to play video games such as Starcraft 2 when it comes out, programs like word and excel, using photo editing software like photoshop, and doing a light amount of video editing. So my questions are: 1. do i get the 2.26 GHz or the 2.53 GHz macbook pro 13"? 2. should i upgrade the hard drive in either case from question 1, or should i wait and eventually invest in a 7200 rpm HD? thanks for all your help!
