Sony shows off flexible OLED Walkman concepts on video

Looks like Sony Insider caught some footage of those flexible OLED Walkmans in action during a CES promo video hidden away in the booth. Looks like a pretty sweet riff on the Cover Flow-esque interface that's due to arrive on the NWZ-X1000, but there's not much else to go on -- let's hope Sony's spending more time getting the X1000 ready to leave that impenetrable glass housing than it is mocking up videos of fantasy tech. Video after the break!
