>>Touch screen on the desktop with a 'upright' monitor would be plain uncomfortable. Are there any reasonably priced 21" touch screen displays:?

>I recently bought a Dell computer for my daughter, and I was very very tempted on buying this monitor, in the end I did not buy for my daughter would probably not use it as touch in the PC (we have a laptop with touch-screen that converts into tablet and we barely use the touch screen and even less as tablet )

I think my daughter has a Dell system like that but I've never looked at it closely (memo to self). Certainly touch screens (with multi-touch and gestures) are more intuitive than a mouse. But, as Al says, it's our physiology that lets us down. We need to evolve longer arms :-}
