I am looking forward to seeing this, as at the moment Windows 8 is a bit of a pain to use on a desktop (or laptop) PC without a touch screen monitor.
It has to be worth a look anyway!
I'm in this camp. On touch enabled devices W8 is very clever, but on multi monitor desktops, which I have at work and at home, it brings nothing new except a bunch of annoying niggles. I'm hoping W8.1 sorts this so I can finally jump aboard.
