The actual hardware is lurking around the show somewhere on the Sony stand. I'll seek it out tomorrow. It's pretty much a PS2 in a handheld unit.
BTW, I saw the Phantom console today. It's easy to be cynical about it, but they might actually be onto something. The design is quite nice and they have a really good combo keyboard/mouse thing. I was very cynical myself, but after seeing it in real life and talking to the Infinium people, I came away with a much higher opinion of it.
