Right tool...
After using it on the laptop, for half and hour, I'm not upgrading on anything that isn't touch focussed.
Having said that, I am inclined to try out and go for a surface pro if any good. To date my experience of new things is generally good. I hated apple but put aside prejudice to look at a tool for a job. The iPad 3 is excellent for reading and convenient computing of the less productive sort. Can't fault it. The surface appeals as I may be able to code on it in vs studio :)
And metro is bloody terrible, horrible, poor and well I come off the fence when I say diabolical for the desktop. It's simply the wrong tool. And it does break some design rules regarding usability of course. Interested in surface, uninterested in win 8 desktop.
