I have a late 2011 MBP and have just been made aware of the AMD GPU issue since joining this site (yes maybe I have been living in a cave for the last 2 years!). I do know of the problems with the retina displays on later MBP's (although I know it's limited to one manufacturer). I also don't like the lack of upgrade / replacement possibilities. Buying a pre 2011 MBP seems a little pointless. So is the sweet spot an early to mid 2012 with a little Apple Care remaining? I have not heard of them having any significant issues and the RAM and battery are still replaceable items right? I have not checked to see if the 2012 can take 16GB RAM but hopefully they can.
