I'm thinking about getting a new MacBook Pro ( I currently have a late 2009 13" model) and I want to get your guys' opinions on what I should do. I'm considering getting a brand new 13 inch retina or a 15 inch retina from February 2013 for about $200ish more. The specs aren't that too far off, except for the battery life difference of an hour (Maverick's might take of that no?). Anyway, your guys' opinions would help me out! Thanks!
