I’m sure quite a few MBP 2015 users are going to be a little sad the end is near. I loved that machine. I was able to skip the 2017 MBP and go to 2019, but honestly I miss the smaller trackpad.
Still using the 2013 and 2015 MBPs here, had no reason to upgrade. Love them to death, still no hardware issues whatsoever except a new battery. I also prefer the smaller trackpad. Guess its time to gift them to my parents. Luckily, the M1/M2 is finally a worthy upgrade, after years of keyboard issues and unwanted features.
It had a good run! (My 2011 imac died last year)
