I was happy with the feel of the 2017, however after a few months a couple keys got stuck to the point of it being unusable. I took it in for repair at the Apple Store, and after repair, touching the ID sensor would cause the machine to freeze. Soon after, more keys started getting stuck and I just put the thing in a drawer and pulled the 2015 back out, which is what I'm typing on to this day. I've been using Apple computers exclusively since the lciii in the early 90s, but my next laptop will not be a Macbook.
