Surprised to hear this. Back in the Surface Pro 4 days, the hardware was great. I made it through college doing 95% of my work on a Surface Pro 4 tablet with the magnetic keyboard and almost always made it through the entire day without having to plug it in.

My wife swears by her surface pros, and she has owned a few.

I've had a few Surface Book 2's for work, and they were fine except: needed more RAM, and there was some issue with connection between screen and base which make USB headsets hinky.
