Hi, I'm finally going to be trading in my 2015 MB Air and decided to go with the 13" MacBook Pro TB (don't care for the new Air). My question is should I get the 2018 model or 2017 model? I'm probably going to get a refurb from Apple but not sure which one is better??? I keep hearing there was a lot of problems with the keyboards, so not sure what to do. Any help would be greatly appreciated. Thanks!
