I'm going to buying one of the current generation MBPs. I keep my computers for a long time (currently typing on my late 2006 MBP), so I want something that'll last me a while. I'm debating (like many) retina vs non-retina. One comment in one of the early reviews was a snarky comment about the non-retina MBPs--the reviewer stating that they "knew which way the wind was blowing". Do people think there is a significant chance that the non-retina MBPs are going to become obsolete more rapidly due to many programs being made to run on retina displays, and end up running more poorly (or not at all) on non-retina displays?
