Scroll forward to 4min in the video for a review of the Sony NWZ-X1050 oled walkman. Sony is going to sell only 1000 pieces on the German market, probably it's because the oled screen is hard and complicated to manufacture at this moment.
Sony has a pretty huge impressive booth, kind of like typical for Sony. They must be spending millions of euros on this interior design thing, unless they re-use lights and stuff at each conference. Anyways, the Sony hall is big and fun.
