I love my 2015 MB, however I made the mistake of getting 128gb and I never got Apple Care and let my warranty expire, so I decided to take the leap and get the new 2017 MBP. My MBP 2015 w/retina was fast, but this machine is unbelievable. I got the 512 gb version to future proof. The only thing I am not a huge fan of is the keyboard. Is it something that grows on you eventually? By the way, the topic is supposed to be upgraded to a MBP 2017.
