Could people who have tried Artrage running on a Multi-Touch PC screen comment on the benefits or problems?

I'm thinking of upgrading my PC and don't know if I should get a touch screen like HP, Acer and some others have. The finger touch would be nice for other work, but I'm thinking that I'd still need to use a stylus for drawing like in Artrage. So I'm going to try to verify if the finger touch screens can also use a stylus. Perhaps you'd loose pressure sensitivity.
