Yeah, that's pretty cool. I like the fact that it has an MMC slot in it. But you still have to deal with a battery. Someone should figure out a way to harness the spindle to generate power. Or even have an option for a power cable to trail out to the cigarette lighter instead of an audio cable trailing to your audio device.

Still, most people have a USB flash drive they can repurpose, whereas fewer have an MMC card and reader lying around.
