I bet you dollars to donuts it won't do HDMI or HDTV output, and it doesn't even have a slot or the power to run a card that can go to your TV.
EDIT: oh, I see... it's not a real computer per se, it's meant to only be used with a TV. I thought you were looking at something else. This is a different class of machine entirely (more DVD player than computer, IMO).
Should work, but dont' expect much from it in the way of functionality. It says Vista Home, but I'd be wary of getting some stripped down "lite" OS type of deal
