I have a feeling that AoEO isn't going to turn out so good. I mean, it looks really cartoony and will probably be somewhat dumbed down compared to the others so it appeals to more people.  
 
I hope I'm wrong, though. We'll just have to wait and see.

Is this available for the PSN, too, or is it just for the XBL Marketplace right now?

I might get one in the future (a somewhat distant future). I'd use it mainly as an e-reader. I'm not too ecstatic about its other features.
