Last week we pointed to the WinHEC 2007 keynote, but as always not every great announcement make it to the stage. Ricavision showed off a portable electronic touch screen with Windows SideShow functionality, which doesn’t sound like much until you imagine it on your refrigerator. The MK 140 FM Magnet/Scribbler features a 3.5 inch LCD display and 16 hours of battery life. We’ve seen some great Media Center Remotes from Ricavision in the past, but the kitchen doesn’t often get the geek treatment. We could easily see ourselves enjoying life more, changing the music in the house while making brownies.
