We've seen bands release albums on USB wristbands, but now the US baseball league is using the invention as a way to get fans to part with their hard-earned - or at least 50 bucks of it.

The PVC USB wristbands reads from an incorporated 2GB MicroSD flash drive and the two versions available either offer footage of the 2008 State Farm Home Run Derby at Yankee Stadium or the 2008 MLB All-Star Game and pre-game ceremony at Yankee Stadium.

In addition, there's a 2-hour documentary "Yankee Stadium: Baseball's Cathedral" as well as ringtones, desktop wallpapers - and more.
