I haven't been able to install the touch drivers, it works ok out of the box but multitouch doesn't work well and tap (click) doesn't seem to trigger (as I mentioned before).

I found an italian site that has been in contact with n-trig
http://www.windows8italia.com/2011/06/n-trig-non-aggiornera-i-driver-dei.html
and they bacically say they won't make drivers for the TX2, I have mailed them in hope that they will reconsider.
