Absolutely. It now really annoys me that I didn't opt for the bto touchscreen on my xps 18 months ago, although I'm not sure that would have been glass-covered, which may just have meant fingerprint city.
Anyway, yes, a week on my surface was enough to make it really hard to go back to non-touch. Even on external displays it really bugs me - I keep reaching out to every screen going ><. And it certainly works well. Saw a Surface Pro the other day, and even at 1080p resolution the Windows Desktop works well for touch - they had it up at 150dpi I admit, which just made it look 'normal' ... it scales really nicely, unlike OS X on the retina displays.
