Why?

Finger is like mouse pointer. Though it may be possible to put two 
fingers at once. And that is indeed the level of "driver-dependant". But 
otherwise I see no difference with usual screen.

I know at the moment that there are touch screens based on capacitance 
and resistnace network. The later seem to perform better in changing 
environement conditions. There is yet probably very few companies that 
produce touch screens. Relatively few that do them for Toronto, etc. 
This is potentially a big market, but Windows only seems to be used 
there, for now.
