This MBPr 2012 made me move back from MBA + iMac to just a laptop. Before that, MBP. Right now I'm trying to find a lightly used MBP 2015 with R9 and ~2 years of AppleCare left, to buy myself some time to either migrate away from Apple or be positively surprised with a new product that convinces me to stick with them longer. Been a Mac user for well over 10 years now, so the final decision won't be taken lightly. I keep a list of candidates to try, including the Dell Precision 5520 and some Lenovo models. Still I'm bitter about it. As far as I can tell, nothing else I can buy at this moment will match the build quality I've come accustomed to. The user experience of (now) macOS is steadily declining too, but not to the point yet that Linux looks like an improvement. I'd fancy BSD more, but that limits the hardware options even further.
