I have a 7" Xenarc TS, and the software is alright. Not perfect, but not bad. I had an issue when I left the screen plugged into the mains for several days and the software stopped recognising it and it didn't work. Plus, every time you unplugged the USB cord or switched the screen off the computer froze. I unplugged the screen from power and now it works fine. I unplug it every night (like you would in a car - completely cut the power) and it's fine now.
