For years, Sony has been scrambling to regain its position at the leading edge of music players. Now, that scrambling has produced an egg — a $399 dancing egg that flashes, rolls and flaps its plastic flippers to the beat. Before you think the Walkman pioneer has finally cracked, it’s worth noting that the Rolly is an amusing and somewhat educational robot whose moves can be programed using a PC. And the gadget certainly is a conversation-starter if your dancing hamster has run off. Even if you need a robotic egg to be the life of a party, though, it’s hard to justify shelling out $400.
