I had my SB Pro replaced a few days ago by MS. I use my laptop a lot, easily 6-7 hours per day so it gets a lot of heavy use and in a lot of different situations so I am always closing/opening it which left me with a ton of sleep issues. So far this new one has been flawless. Not a single issue waking, crashing, etc...I had one crash when I first got it out of the box but was that before the updates. My old SB Pro had a myriad of never ending problems that never were solved regardless of the updates. The only difference between my old and new is I have not yet joined this to my domain at the office. Should not make a difference but other than that its just like old laptop. Office 2016 installed via 365 and Visio 2016, nothing else.
