Surface pro 2 here with windows 10 on it, and I have to say, one thing aside, I really like it, I've already installed it on just about everything from tablets to media centres and its good, looks good, and runs good too.
Only niggle is the bloody Graphics drivers MS pushes out, serious problems here, that last firmware update has done nothing to fix them. Strictly speaking its an Intel thing but since MS goes out of their way to stop us using the Intel drivers and actively removes them at every opertunity I'm going to lay the blame at MSs feet. Fix the drivers!
I don't have the issue on an AMD based system, just the Microsoft branded Surface Pro 2 tablet with the MS drivers
