My 13" 2011 MBP still works flawlessly, depending on what I'm trying to do with it. Basic web browsing, playing music with iTunes, no problem. But trying to build modern Wordpress websites with it doesn't go so well, and the latest Adobe apps don't work at all on it.
But I do think that for a computer to still be usable after 10 years makes it a very good one. My first laptop was an HP Compaq Presario 15" with Windows 7. First battery died after a year, second one, also a year. Within those first 2 years, screen problems that I just couldn't figure out, even with the attempted help from a repair shop. I could also go have breakfast while I waited for it to boot. My 2011 MBP battery lasted 9 years and went over 2000 cycles before it started to show any signs of weakness. I eventually replaced it myself for €80. So yes, these were the last truly user serviceable Macs that Apple made.
