You would still need a TV to set up the systen sadly.I'm really considering buying one after E3, the refurb price is just right. Feels good to be excited about Nintendo again, I had given up around the time GameCube's reign was coming to an end.
One of the biggest draws for me is actually the GamePad, you see, I don't have a TV. So is it really true most games are completely playable without one? I could just turn on the GamePad and play? If so, what an awesome feature.
But yes, you can play most games full from the gamepad after that.
