I'm planning on purchasing a H2O. I had some Sony readers way back when they came out, switched to tablets, and when I found waterproof readers, I wanted to get one. I would be interested in running Android on the H2O, but I don't know too much about modifying Android so it could run on a Kobo reader. But I found this Blog:

Angor is running Android on an Aura HD, so I think it should also run on the H2O. Only thing I don't know is whether or not Android can be fully controlled because H2O only has single touch on infrared and Aura HD has multitouch on capacitive.
