I assume you had no problem getting the HDMI part to work, but did you calibrate the AR1100 touchscreen controller yet?

Newegg had them on sale last month for $159, and so far I find them perfect for HomeAutomation/Security/etc. control. Build in speakers + webcam allows for lot of extra options. Running mine with ImperiHome right now, which is able to use the webcam to detect motion and turn the display automatic on approach.
They don't have a VESA option for eays mounting on the wall, but with a little DIY that should not pose a problem. For the moment I'm still using them on tables/desks, and they also come in handy for Skype webcam calls, and more.
For HomeGenie you can just run the webinterface inside Chrome, or use the dedicated Android app.
