| 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 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 SanDisk Sansa Clip+ is an excellent successor to the line, offering a fitness-friendly design with a built-in belt-clip, a simple interface, solid sound quality, and plenty of handy features--all for an ultralow price. It's an unbeatable value. | 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. |
