I had a Surface Pro 3 for a while and though I got Linux running on it, I never managed all the tablety stuff working properly. Rotation, Pen + Touch input (at the same time without randomly cutting out!!), auto keyboard popup on input fields with no keyboard connecting, the keyboard actually working after being removed and reconnected, etc etc...

It was a great machine but Linux lacked support for this type of support in many ways. I wonder if this has improved as this was many years ago when the SP3 was just out.
