The Bottom Line	It's an MP3 player. No wait...it's a speaker. Is it a robotic dancing egg? Actually, the Sony Rolly is all of those things. But mostly, it's just a pricey musical toy for gadget heads who have everything--including some cash to burn.	It's an MP3 player. No wait...it's a speaker. Is it a robotic dancing egg? Actually, the Sony Rolly is all of those things. But mostly, it's just a pricey musical toy for gadget heads who have everything--including some cash to burn.	The Dolphin Swimmer MP3 player is an innovative waterproof MP3 player that should appeal to surfers and swimmers that want some tunes to follow them into the water.	The NW-S200 Walkman proves once again that Sony knows what it's doing in the hardware department; fitness-minded users should take a close look at this flash MP3 player. But make sure you're comfortable with SonicStage before you commit.	The SwiMP3 could add some fun to your swim routine, if you can afford it--just beware of potential nausea-inducing inner ear imbalance.
