You play with the Nintendo portable when you're a younger kid, but after a while, most guys -- and we know guys in the industry, and really hardcore gamers, may play some with the Nintendo IP -- but by and large, we don't see a lot of older guys in airports playing, as you do with younger kids.
Of course, these demos have been here before and the DTCP-IP technology behind it isn't particularly new either, so why could 2013 finally be the year we see these features roll out from major providers?
