Although I don't know why, I think gogos are the best thing ever. I just keep trying to work out how to use them. Maybe now I know - they'd be the perfect counters for a board game that uses the iPad as the board. They'd look gorgeous sitting on there. We'd need to work out how to make the iPad think they were fingers - maybe some sort of electrostatic sausage skin - and to remember which was which. But I suspect something gogo-like would be another perfect iDevice companion (like measuring pebbles.)
