I just find the touch experience on Surface to be completely lamentable and the hybrid desktop-tablet interface boggles my mind. I agree the hardware is fantastic but I find Windows 10 intolerable.
For example, the only way to get a slider to adjust display brightness was opening the OS display settings. At least that was the case the last time I tried it.
It's not a slider but it does the job well.
That said overall the tablet experience on Windows 10 is not ready for prime time. I get weirdness with the on-screen keyboard as well as quirks with Explorer and so on.
