I was absolutely ok with repairability of 2013 pro models. But what they did with new keyboard design is awful. I write this now from my Dell XPS 13, not from my MacBook Pro different models of which I used for > 5 years.
Writing from my 2017 MacBook Pro. Apart from the keys being louder than before and my nagging fear of an errant crumb or cat hair I'm happy, typing is crisp and maybe faster for me than on any other keyboard. I move my hands less. In comparison my regular Mac keys now feel loose and smooshy, almost as if they'd been produced by the Haribo Gummy Bear factory. (Not that this is a horrible feeling. I miss gummy bears; can't they make them out of xylitol or something?)
Have you had issues with OS X? My fiancée's laptop needs to be rebooted every time it goes to sleep, and both her and my own older (2015) MacBook Pro want to boot from the recovery partition every time. It's a pain in the ass and a terrible degradation of experience.
That sounds awful, but no, I haven't had that kind of problem before. Sounds like you might want to think of reinstalling/upgrading the OS? I've never heard of that issue though, sorry.
maltitol gummy bears do exist. Search for "sugar free gummy bear". Eat in moderation at first - some people have a very intense bowel reaction to them.
