Installed 10 on my Surface 3 and was initially very impressed but the reduced functionality of Onenote (on the tablet...where's the bloody wheel gone!), Onedrive (no control over what's happening) and updates (is auto everything the only option?) gave me the irits. Uninstalled and back to 8.1.
My impression is that 10 is not quite tablet ready.
Nothing is easy though. The uninstall was quick and painless but now Mail/Calendar/People doesn't work. Off to sort that out now......
