I'm alright Jack ...
Surface Pro 4 owner here. Bought it in January (2017). Worked okay out of the box. I wouldn't say that it ran hot. Although the fan came on frequently, which is irritating in a quiet room.
Creators Update took care of all that ... Post-update Windows Hello not working. Days spent on tinternets trying to find the cure. Lots of solutions proffered. None worked. I ended up running a Factory Reset of the tablet, followed by another update to Creators (of course). And everything is back to working again.
Really, Microsoft? Really? 2017 and you're still at it!
