no reason it shouldn’t work. the Tablet OS is basically XP Pro with some extras. i ran it fine on my Toshiba Tecra M4. if the tablet or what have you runs on a fully functional install of XP then you should be fine.
the tablet interface is absolutely brilliant for apps like max/msp. much better than a mouse and much more intuitive and fun once you get used to it… a wacom tablet, on the other hand, just didn’t do it for me after i tasted a tablet pc.
