What the heck is the point of windows 8 unless you have a touch screen monitor?

Windows 7 is an awesome OS. From what I can tell, windows 8 is just a bunch of boxes for touching and scrolling to a new screen with boxes, which is great on phones and pads, but for a regular setup, I really don't see what the advantage is supposed to be.

Windows 8 isn't even retail yet so why would they do that?
