Scratch That Remix Itch With Art Lebedev's Plastinkus DJ Cards

The Art Lebedev shop, which brought us the beautifully designed but economically forbidding Optimus Maximus keyboard, is now moving into the toy business with a portable DJ scratch pad the size of a credit card. They call it the Plastinkus, and it's supposed to produce true music sounds.
From a quick look, it appears to include a tiny, hair-thin turntable but there's no word of inputs, outputs, EQ knobs, or a volume fader. But hey, if you can get any notes to work on a slice of plastic, it's probably worth the $5 it costs. It's available in 40 different colors.

If the Lebedev folks haven't thought of it already, maybe they could figure out a way to include a song on the card, then make it moddable and easy to transfer. The prices for storage has come down so much that you could easily pare it down to a super-portable music/DJ player. Oh, I know there are portable DJ players out already, but maybe one could be available for less than half a grand?
