TouchRevolution’s Tru-Touch multi-touch/touchscreen monitors are one of the best I’ve seen in my life. These are basically standalone multi-touch monitors you can use along with your existing Windows/Linux computer (or laptop).
In comparison to HP’s touchscreen all-in-one desktops I tried at BestBuy, these Tru Touch monitors are “truly” multi-touch, allowing you to transform your existing desktop into multi-touch madness using fully capacitative screens.
What I like about these monitors is the fact that you can get them separate from the computer. But you will need OS specific drivers (and currently drivers are provided for Windows/Linux) to make the multi-touch work but Windows 7 also has multi-touch support so it should be no problem.
There are 3 different flavors of the Tru Touch monitors, 15-inch, 19-inch, and 22-inch.
You can check TouchRev.com here as they will go on sale shortly.
Zooming works nicely, just as it should on theses TouchRevolution Tru Touch monitors.
Two hands works well also.
