I have a touch smart tx2 1370us. he windows 7 operating system became corrupted and my backup disks didn't seem to help so I migrated to Windows 8. That lost me the multitouch interface, the dedicated buttons and the finger print reader. When 8.1 came out, I went ahead and uopgraded. The computer wouldn't start normally, so I backed down to Windows 8 again. I've just about gotten the updates back to where I was before the failed 8.1 trial and would really like to regain the full functionality of the computer. other than the specific drivers for this computers hardware, 8 seems to work great for the tx2.
I saw a little chatter concerning the pre-release windows 8 (beta) for developers and this computer, but do not know of anything done for the subsequent full release systems.
