The buggy build of ICS on the Touchpad we saw earlier has been let out to public. Among the things that currently don’t work are Market access, hardware accelerated video and the camera. The project is developing fast so fixes should be expected really soon.
The source code for the release has also been outed so if you want to play around with your own version of the build you can do that quite easily. Triple boot of webOS / CM7 / CM9 is possible but the developers are currently recommending against it.
