I am in the market for a new computer, after an unfortunate water spill on my 2011 mba 13, and would like advice on which rMBP to get: 1. A refurbished late-2013 rMBP 13 with 2.4 Ghz i5, 8GB RAM, 256GB Iris configuration for roughly $1,500 (inclusive of taxes). 2. A used mid-2012 rMBP 15 with 2.3 Ghz i7, 8GB RAM, 256GB, GT650M with Applecare till June 2015 for $1,600. Laptop usage would mostly be watching movies/tv shows, web browsing and some occasional gaming, such as League of legends, which i'm sure the rMBP 13 can easily handle as well. Portability isn't really an issue here, since I usually bring my iPad mini and would bring my laptop along only when i have group meetings. The only thing holding me back from the rMBP 15 is that it's essentially a two years old computer and used, whereas the rMBP 13 is very new. Which do you guys think would be a smarter buy?
