So, I will be going away to school in August (Penn State!)! I've decided I want a Macbook Pro and I feel the 13" will be perfect for me! The only thing I'm stuck on is which model I should go for, the one with the i5 or i7 processor? (Planning on getting 500GB of hard drive space...possibly 750GB) I'm not really a gamer, I'll probably download some games from the new Mac App Store but nothing crazy! I'm a biology major so I'm not really going to be doing any video editing or Photoshop, although I may install Photoshop to mess around with! I'll manly use the computer for Word documents, internet browsing, video chat and music/videos! (Possibly thinking of jumping into iOS development while at school) As far as the ram goes, I won't be upgrading to 8GB from Apple, I'd probably purchase it somewhere online and install it myself...will I notice a big difference? Explain. I plan on having this computer for all 4 years of school and possibly some of medical school afterwards, I want to make the most of it! Thanks in advance!
