I've a feeling you're in the minority though. It's not that touch becomes the main method of interacting with Windows. It's that it becomes convenient for some things, particularly scrolling.
I have a laptop/tablet hybrid. Sadly it weighs too much for me to actually want to use it as a tablet. So I never use the touch screen, I have a wireless mouse that I use to scroll. Being touch is mostly annoying when people point at my screen and click things.
I still think the surface book is cool, but the weight factor is probably my biggest concern for the tablet mode.
