I admit that I'm really an eyecandy eye candy and XGL fan under gnome.... I like this guy's setup with it up with a touchscreen. There's something really nifty about physically spinning your desktop around with the touch of a finger. Course, from everything I've read ergonomic-wise, touchscreens suck (or really build up the shoulder muscles). Still, visually very cool :)
really it's not much ergonomic...
I bought this to over-use my hands... I was so bored with the mouse... but a new multi-touch screen is comming, look for it on you tube.. you will see. its really the future!
