I have the non-retina version of the 2012 and it is still going strong. Battery is still fine, screen has nothing wrong with it, and I upgraded the RAM to 16GB as it only came with 8, then shoved in a 1TB SSD to replace the incredibly slow 750GB hard disk. Dual boots to Windows 10 and all is great! I honestly don't know what I'm going to do when it breaks because I don't like the work MBP I have (2016 too) and I don't like the direction macos is going. I'll really miss this 2012.
