First let me welcome you to our little web commnunity! Glad to see you made it over here from I-Club!
To answer your questions you asked there.
The touchscreen works great. It comes with a calibration utility similar to the configuration you would do on a palm pilot. There were a few bad units sent out in the beginning, but I believe that was 3 in 40+ units. Not bad for a very new company. Most didn't have a problem with support but InFix had a problem with them. I believe it was ultimatly resolved.
Everyone else seems to be pleased with them. I'm certainly happy with mine. Here are some pictures of the Xenarc as provided by our own Krazy Nemisis.
