With Windows 10, it isn't all about the desktop. Microsoft is making refinements to the touch-side of things too, meaning tablet and hybrid users have some cool things to look forward to. Today, Microsoft officially revealed a new Start Screen for two-in-one devices.
This new Start Screen is brought to the user with the help of "Continuum", which will detect what hardware you're running and adjust the UI accordingly. Microsoft will talk more about this feature soon, but for now those are the baseline details.
