Cyanogenmod on the Touchpad alpha release: WIN.

The developers say it's buggy, but I'm happy to report that even at this alpha stage, it's very usable. I didn't have much time to play with it this morning before work, but I did get as far as booting up, opening up a few web pages, and installing SlingPlayer (which seems to work fine.) Swiftkey complained about not being optimized for tablets, but seemed to work anyway -- I'm guessing it's just lacking the split thumb-typing mode.

Overall speed is faster than Webos, which was to be expected. They did say battery life is really poor right now, but I rarely use mine on battery for more than a few minutes anyway.
