Desktop OS"s really aren't made for touch screen devices, it just doesn't work very well. It sounds great but really, it isn't.
I think you're better off waiting for the new Windows tablets with the Metro interface and wait for MC to update to run on it.
Agreed. I have a couple of the older style Windows tablets (the ones that shipped with Windows XP Tablet). They weren't anywhere near as good as I'd hoped, and they're both collecting dust (the newer of the two has been upgraded to Windows 7, and that made it marginally better, but it still isn't good). Way too often, you end up having to either plug in a mouse or pull out the magnifier to get things done. The on-screen keyboard is dismal.
I've also tried out one of the newer Windows 7 "slates" that shipped last year. A little better in a few ways because of the capacitive touchscreen, but only marginally. The other problems all still applied, and that one couldn't even use a good stylus.
We'll have to wait and see how the new Windows 8 ones work, but I'd wait. Now would be an
awful time to buy a Windows tablet.
EDIT: However, on a large-format system with a good touchscreen, Windows 7 is pretty decent. My
Perceptive Pixel 27" system works great. The on-screen keyboard is still basically-useless for anything other than a single word or two of text, but otherwise it is very usable. I think Windows 8 will make it much, much better, so I'm looking forward to that.
Can't carry that thing around without a cart though.
The PC weighs a ton and the screen two-and-a-half.
