Palm brushes don't register on OS X

That's why I wanted more clarification on what you're comparing it to. The only positive I can see of a touch screen compared to a __good__ touchpad is that you can see the content below your fingers as you interact with it - I wager it's the difference between the Intuos and the Cintiq.

I don't know if that's a big enough difference for most people to have to deal with all the negatives that using a touchscreen on a computer monitor comes with. For me it's not.
