saw some of these devices today in the middle of manhattan, around 40th and 5th. in broad daylight and all...big store was clearing out all sorts of merchandise.
some of the small devices look like xboxes and is called "x block", it has a gun and a controller, i assume has a flash rom with some games (old games obviously) hardcoded on it.
and also a playstation lookalike controller, with another small controller attached to it. the box contains pictures of KoF characters.
all are made in china.
