>Win8 is optimized for touch, but doesn't require it. I don't have touch on my laptop and Win8 works just fine.

As long as you skip most of the features of Metro and head for the desktop.

Isn't Metro just grand?

>>Obviously I am not fully up to speed on Win8 but running Metro on a desktop doesn't even make sense to me. Isn't touch a big part of it? If I upgraded this machine to Win8 would I suddenly be able to do things by touching the monitor, dragging, growing/shrinking, etc.? One thing I love about my setup is the two large monitors and I sure don't want to run out and replace them with touch-sensitive monitors (if that's what I would need to do). Can someone please clarify this for me?
