Yes you read it right... one of the things that emerged at WinHec was a Wireless Fridge Magnet which leverages the Windows Vista SideShow platform (back story about Vista After Hours) that can stream content from your Vista PC to the device. Cool (no pun intended). The company behind it is http://www.ricavision.com.
Hang on a minute... SideShow? Was that another innovation - well I'll be! (back story about Microsoft innovation here).
Ian Dixon has more details and yes I am trying to get hold of one.
