I have a 2011 13" MBP but I am in doubt whether I should upgrade, but was thinking of upgrading to non retina MBP 2013 is worth the upgrade? the difference from HD 3000 to HD 4000 is too big? on the iris graphics we only noticed the difference is on games right? i little afraid about the 13" rMBP because I do not like the idea of having the RAM soldered and to update the HDD is very expensive. I do not think its vary safe and durable, maybe its things of my head.
