Roll up for Sony's Rolly

Since it made its first appearance on the Web, no one really knew what to make of the Sony Rolly -- it's a music player that kind of dances, kind of rolls around. Actually, it's a palm-sized, robotic, dancing boombox. At least that's what Sony tells us. At first glance it's hard not to smile. In fact, it's hard not to keep smiling. There's something cute about Rolly, but we're partly smiling out of sympathy -- because it's hard to determine exactly who's going to buy one.
