I moved over my personal MS Surface Pro 1 a couple of weeks ago, and think its pretty nice. I didn't like Win 8, but 10 is good so far. Work computers are not converted yet, but I imagine if I get a new one this summer it will have W10.
If you use roaming profiles there is an issue with W10 Edge (the browser ;-) ) and Cortona.
Microsoft Edge and Cortana crashing for users with roaming profiles.
The issue should be fixed if you are part of the windows insider preview programm.
At the moment the issue still exists, if you are not an early bird.
And FYI... Checkers across the display with an NVIDIA Quadro card is a known driver issue. You can install an older driver to eliminate the issue or wait on a new driver if the issue isn't too bad.
