But I am wondering if a reasonable or even better solution is an appropriate touchpad or even Android or iPad touchpad app.
Right now there are two (maybe three) touchpads quasi made for Windows 8 that I would like to try.
* The Logitech Wireless Rechargeable Touchpad T650 -- a huge touchpad with Windows 8 gesture support
* Splashtop Win8 Metro Testbed for Android and iPad
* Unified Remote for Android and Windows Phones
I haven't used Windows 8 more than three minutes, and I haven't used these alternatives to a touchscreen monitor, but I like the idea of having a 4" to 7" phone or tablet screen that mirrors the Windows 8 screen but lets me keep my finger flat on the table, pointing to a smaller screen now in remote touchscreen mode and able to get feedback to where my finger is either by seeing a "mouse pointer" move on the screen, or just by looking at the phone or tablet my finger is on and seeing the screen there.
