Photon definitely works on iPad. I've spoken with the developer & I was so excited when I was in the Chat Room that I didn't find the Keyboard Icon on the UR cornet of the iPad. That activates the keyboard--I was right, the touchpad doesn't. I've not had time to go back in, but I think that will make it workable. Not I just need to find a chat & try things out.

I don't know about other tablets that don't support Flash.
