I absolutely love my MBP, the 15" retina from 2012. I just spent $90 for a replacement battery, and after 2 hours of disassembly and reassembly, it's back to being a fantastic workhorse.
But there's no way I'd buy a new one for myself today.
Did the same thing. Not even considering upgrading (although the 32GB of RAM is nice).
Probably one of the reasons why these laptops are so expensive.
