Touchscreen for video/audio editing?

Hi all,

I am wanting user opinions on touchscreen monitors. Here is a post from another forum. If you have any information for me let me know.

I'm thinking of getting a touchscreen for doing video work with Vegas and music production with Cubase. A friend of mine who's a photographer said that you only want a Wacom. I think he has this model: http://www.wacom.com/cintiq/21UX.cfm

My questions are, how would the workflow be with one of these, and is it true that you only want a Wacom? I get the sense that with Cubase I will be able to do work more quickly and effectively, since what I do there is A LOT of very precise editing and micromanaging of events. With Vegas it might be quicker too although I do less microediting.

The problem with the Wacom is that it's so damn expensive. On Newegg there are several touchscreens of different types that are much cheaper. Anybody have some insight into using these to do work...or if it's a good idea to begin with? Oh, and btw, alternative input method suggestions are welcome. Right now I use a Fingerworks iGesture Touchpad for general purpose computer use. Although I like using a mouse better when I do work with host apps.

The Elo touchscreens at Newegg seem like they might be decent. Although I'm wondering if I rest my arms on it when I'm doing work with it if will it mess up the pointer position.
