Sony decided to rock out at CES this year with their entertaining Rolly display. These egg-shaped digital robotic music players were out in full force, flashing their lights, and flapping their wings to the beat of Christina Aguilera's "Ain't No Other Man." Each egg "dances" to the beat of the sounds coming out of the side speakers, as songs can be downloaded from computers or played via bluetooth. The Rolly includes 1GB of memory and still has yet to hit store shelves in the US. I can't say I personally need or want one, but you can't help but be mesmerized by their moves. Have a peek at the video below, and let me know what you think!
