Have you lost your 128MB SD card? Want something that has much more capacity? Fear not, the mighty 500MB DataPlay disc is here! "Techmoan" presents another data storage device that lost out to the rapidly increasing depth of Ye Olde SD card. It's almost the right size for "Cherry 2000," that 1980's "companion doll" featured in the 1987 movie of the same name. Like MiniDisc, this tiny wonder disc was a caddy-borne data device, which I've never heard of, either.
