Quarter-sized CD's?

Anonymous Coward writes: "The Denver Post is running an interesting story about Dataplay, Inc. This Boulder, Colorado based company aims to supplant the 20-year-old CD with a quarter-sized (1.5" x 1.25") optical disc that can hold 500 Mb of data. Players and media (already supported by 4 major record labels) are scheduled to launched 'the latter part of first quarter 2002'." They're cute, but considering that Sony's minidiscs never took off and this format is heavily restricted, my guess is that this will fail.
