I want to buy a 13" Pro but I will also play (very casually). The 2010 model obviously has better graphics but the 2011 model has a lot better processor and is more future-proof. Whatever Apple will release in November or early 2012 I want to keep this machine for at least 18 months. However I am worried about the heating issues from the newer model. Btw, I want the standard dual-i5 2.3ghz with 4gigs of ram (might upgrade to 8 later) and I really want to upgrade with a 128 SSD. Would this compensate the lower GPU ? It sure made wonders on the Airs.
