Looking for feedback by other Artrage users as to how you like using Artrage with a MultiTouch monitor.

There are some available for the desktop much more affordable than the Wacom tablets.

I'm wondering for my Mother who was quite capable with natural media and think a PC with artrage might get her more involved.

Is it usefull with just your finger?
Is multi-touch a distraction or a problematic with the drawing program?
How accurate is the stylus?

Also, I'm not sure if the optional stylus used with these new optical multi-touch screens has any rightclick ability. Wonder if people find it an issue.
