There is also the OpenPandora ( http://openpandora.org/ ). It's more expensive but more powerful and supports gaming too. "Play, Code, Compile, Surf the Net. Anywhere."
Plus, also, if you go back in time some years and pre-order one which you find yourself still waiting for, it can induce a kind of bitter note. I'm just saying. Sigh.
But they've really come a looong way, those guys are nothing if not persevering. Truly amazed, but a bit sad that the wait turned out to be so fantastically long, of course. Hardware like this doesn't age too well.
