Good to hear! My main computer is my desktop, running Mint. (I’m using it right now.) But I also have a Surface Pro 4 that I use for work. It has no problems and works fine on Windows… but I have been wondering if I can move that away from Windows as well. So its encouraging to hear that it has worked for you.
Does Mint have good support for the stylus and touch-screen on the Surface 4? (I imagine the Surface tech might be specialised to Windows a bit, so I wouldn’t be confident those would work immediately in Linux.)
