The ROM appears to be usable, but given how it’s considered to be an extremely Alpha build, there are quite a ton of features that do not work just yet which includes hardware video (which prevents Netflix or HD YouTube videos from playing), the camera, and audio just to name a few. However if you just cannot resist CyanogenMod 9 on your HP TouchPad, you will be able to find the download at RootzWiki along with additional information on what works and what does. Alternatively there’s a thread going on at the XDA forums where users are discussing their experiences with the Alpha build of CyanogenMod 9 for the HP TouchPad.
