Good photo essay on ZDnet showing what we're up to:

Kind of funny that instead of photographing a CHUMP Symbol Palm unit being used by an umpire on a match court, they grabbed the test unit off my desk for the photo shoot - the label at the top of the unit clearly reads "BRODER * TEST".

Also from The New York Times:
