I've acquired the EP121 four weeks ago and it's going great! However, I have found that when I try to use the pen, my palm tends to cause quite a bit of trouble so I have to switch the touch input off. But when I'm not trying to use the pen, it's obviously useful to have the touch input on. Having to go into Control Panel to change this everything was becoming a pain very quickly. Since I never use the Flip3D feature, I thought I should remap the "Home" button so that I can switch the touchscreen off/on in one button press. Unfortunately, as far as I'm concerned, no existing solution seem to exist. I have managed to write a lightweight program to achieve exactly this. Since I've found this forum very helpful so far I thought I should share this on here just in case someone finds it useful as well. ToggleTouch When this program is running, the "Home" button on the tablet is reprogrammed to toggle the touch input state. I've tried to make the program as small and lightweight as possible, and it just sits quietly in the background. As far as I've tested, it uses very little CPU time and memory and shouldn't have a major impact on battery life. Just download the zip, put ToggleTouch.exe wherever you find convenient, and run it. There's no dialog box/window/taskbar icon, just press the home button to see if it works. If you want to quit the program, run ToggleTouch.exe -exit or kill the process in Task Manager. If you reboot your computer the program will NOT be loaded automatically. If you want it to run on startup, you can find good instructions on Google. This is a free software under the terms of GPLv3.

Source code is available at http://hydrogen.saran.in.th/ep121/toggletouch/src.zip Disclaimer The program uses a low-level keyboard hook to achieve its trick. I have tested it myself and it seems to work, but I accept no responsibility whatsoever if your system stops responding to key presses/sets on fire and explodes/murders you. If in any doubt, check out the source code and compile it yourself.
