Might be too early in the lifecycle to ask this, but I'm starting to consider whether to keep my first-gen (2012) MBP Retina (8GB RAM, 256 GB SSD, great shape) for the long haul or sell it while it's still under AppleCare and get something new. My only consideration is long-term support and reliability; I love the computer and it still does everything I want it to, but I don't have any Apple stores near me and realize I can't do any work on it myself. It looks like they're going for $1100-$1400 on eBay, which would put me in the ballpark of a new 13" Retina. Any opinions on how well these are going to hold up, and whether there are sufficient changes to the newer, lower-end models to extend the useful life? Do values tend to drop after the warranty expires? Thanks for advice! I've been a long-time Mac user but never sold any of my old machines (as my slow-as-molasses 2008 macbook can attest).
