Long-time OS X user here. I bought my wife a Surface Pro 3 recently. We both love it. The pen is beyond excellent. The touch-screen works as well as Apple's own touchpad. The new start screen works as a fine replacement for Dashboard. Installing CygWin lets me use all the linux tools I want. I'm sure the new start menu and continuity stuff in Windows 10 will be just as good as with Apple, if not better. Sublime Text works fine on Windows, my son uses it all the time with CygWin. Haven't had any driver issues, granted we're only using the built-in hardware. I even installed Emacs and it works just as well as on my Mac.
