I was one of those annoying Apple evangelists for years. My 2010 MacBook Pro was my baby and I loved it. Eventually it got to the point where I had to replace it (after 7 years!) and when I went to look around at the new MacBook Pro range, I was so disgusted by all the problems that I ended up getting a Dell XPS 13.
I consider my original MBP and the following models to be some of the best laptops you could buy at the time. If I could buy a 2015 MBP with a modern processor I would do it in a heartbeat.
Meanwhile I wouldn't recommend the current range of Apple laptops to anyone.
Just curious: What's different about the processors in the current MBPs vs those in the 2015s in terms of how it affects your work - or whatever else you're using your MBP for?
