So I was so psyched for the announcement today because I was interested in getting the 13" retina model, but now I'm a little unsure. The 13" only comes with a 2.5 GHz dual-core i5, while the 15" has a 2.3 GHz quad-core i7. That looks like a pretty big difference in processing power, not to mention the discrete graphics. I'm just a grad student who'll mostly be using the MacBook for word processing, web browsing, notes and such, but once in a while I also need to do some HD video editing in Final Cut Pro 7 or like to enjoy a game of Portal 2. (Fairly basic FCP editing though. I don't use Color and those other apps. I just prefer FCP's interface and flexibility to iMovie basically.) Would an i5 really be powerful enough for me? I'm coming from a 2010 MBP with a 2.66 GHz dual-core i7 which unfortunately got stolen, so I'm a little antsy about getting a "weaker" computer even though I may not have needed all the power of my original machine. The portability of a 13" is very attractive to me after lugging around a 15" for my past 4 years of collegiate MBP ownership. Maybe having a SSD would make up the difference and I don't need to worry?
