I'm looking to buy a second hand 13" MBP with retina display. But I don't know whether they're all the slim versions that are the same as available to buy today. For instance, is a late 2012 the slimmer version of the MBP?
I suspect that it'd better for me to get one built as late as possible due to the different chips being used across the years?
