I need to upgrade from my 2009 13" MBP. It's starting to get slow and can't handle stuff I need. First I thought of a new 13", but I know the 15" has quite better performance with the quad core. I'm looking at the 15" with 2.3 GHz processor, 16Gb RAM and 256 Gb harddrive. I'll use it for: 1. Just the usual stuff like surfing, studying, watching movies. 2. Music production with Logic Pro 9/X. 3. No photo/movieediting. No games. I want it to last for about 5 years. That's why I took 16 Gb of RAM. But is it overkill for my needs? I don't really need the retina since I dont edit movies/photos, and most often I'll use a bigger external screen. But I do need to carry it with me sometimes and a few month a year I'll not have external. (It's probably not an option to buy the old MBP and upgrade it tough).
