@Crabby…a touch screen would be useful if this were say…in the Kitchen…you could easily use it to (slide finger) flip through recipes and such. Also, if you put the upcoming Windows 7 on it…it will have much better support for touch throughout the OS. Right now, most OEMs have their own custom touch programs for customers to use.
Although, I understand your argument w/ Fingerprints. If you are using this machine to watch movies, obviously you wouldn’t want fingerprints on the device.
