So don't use it! I never understood why consumers would not want a feature, I'm sitting at my breakfast bar having breakfast with my surface pro 4 in front of me, the absolutely logical way to navigate is with my fingers on the screen. If we are getting rid of useless hardware, my vote would be to get rid of the trackpad which in all these years of existence I've probably use a dozen times.
Since the surface devices have been released I doubt I would ever go back toa laptop, but if I did there is no way in hell I'd get one without a touchscreen, it's just so damn convenient.
I don't have any to not use!
Can't do that with an all-in-one.
(Speaking of getting rid of hardware, my vote is to trash the mouse and keep the trackpad. It actually just occurred to me yesterday in fact that I've actually become more adept with the trackpad for gaming than I am with a mouse. I remember when I thought that would never be the case...)
