Thats right. Its true. Once the WELCOME BACK screen appears, THE SCREEN BECOMES NON-RESPONSIVE. Some "Welcome Back!". This is a serious issue. I am not buying a keyboard. Ive spent enough on Microsoft. My Surface 3 has now been sent back for a full refund. Windows 10 is NOT SUITABLE FOR TABLETS and this should have been addressed before people part with their hard earned money. Goodbye Microsoft, you had your last chance and blew it.
