windows 8 with touch enabled devices is another level. even if you only ever use touch so little. with touch and pen it's another level yet.
I've used Linux laptop with touch screen hacked in since 2006. had tons of tweaks. and win 8 still bowed me away. it is even integrated with a remote desktop (RDP) client on ios and android. when i connect to my HTPC in the living room (only place i have a reason to have windows installed) the touch input from the tablet just shine. i can use the remote device as if i was holding a surface 3 or something. there's no hacks and extra menus on the client to do anything. just touch solves all the needs you have to use the box
