I think the Surface Book hardware is fine -- it's just dodgy drivers and Windows 10 updates that cause tons of issues.
With my MBP I can close it and throw it in my bag without a second thought. I wouldn't dare try that with the SB because nine times out of then I'll end up with a dead battery.
I'm really surprised this is still a thing. One of the first things I loved about switching to a MacBook was that the sleep/hibernate functionality 'just worked', while it almost never did on the Windows laptop I had before that.
This was 10 years ago, and even then I didn't understand why a crucial feature like this wasn't given more attention.
