Portable Video Player
'Video iPods' Bring Seinfeld on the Subway
This is interesting.
But I think this player will not became popular in the US as some reviewers said.
Every American people except New Yorkers always use cars. They don't have enough time to watch videos outside.
This player should be released in Japan or some Asian and European nations. Especially in Japan, people spend about two hours for the train transportation everyday. The portable video player is good item in the train.
