So it's time to upgrade my 2010 13" MBP, it's been a trooper but it has got to go lol.. I use it for basic web browsing (just a handful of tabs, maybe 4-8), video streaming, doc editing.. I also do some light-moderate video editing in iMovie and photo editing in Pixelmator (nothing at the professional level, just some videos and pictures of family and events we attend). I play The Sims occasionally too. I would assume the new 13" rMBP would work fine since my old one was doing okay, just a bit sluggish and it starts to burn up the second I open iMovie. If I do end up going with the 13", would you recommend the 16GB upgrade according to my current usage? I don't plan on changing how I use my computer in the foreseeable future. Orrrrr, would it be best just to get the base 15" rMBP? I should also add that the 13" screen size doesn't bother me at all. I actually prefer the smaller size but I'm worried about the processing aspect of the 13" rMBP compared to the 15". Sorry for the wordy post..
