Great OS, I've been using it for quite a while on 5 different computers, two of them used in performing live, has been rock solid for me, almost no issues. Auto updates are on.
It's especially rewarding if you come with an open mind and don't try to make an XP out of it. Some things here are just great - the File History backup, the new OneDrive experience is cool. Cortana is also great (not because you can talk to it, that's stupid, but because you can type, it makes search and things like setting reminders way more sensible). And so on.
I have yet to encounter any hardware problems with it. In fact, it's been way better than Mac OS in this regard.
