Personally I don't think a touch screen "works" sensibly on a desp top machine.
I have Windows 8 on a laptop and find it "clunky" (it doesnt have a touchscreen).
I am a quite happy user of an Android mobile phone and an Android tablet - they do "work".
I can see how a machine with a detachable screen (such as the HP Envy x2) works with a detachable screen so it is either a tablet or a laptop but I still prefer the laptop (non touch screen) for most serious uses.
