Well, I used one today and I thought it was kinda nice. Then again, I'm one of those chumps who loves his iPod Mini and wouldn't trade it for the world. The Shuffle is like some of the other USB or Flash music players, except that it's got the Apple branding and works with iTunes. It's a smart move; there are probably people who love their iPod for riding the bus to work, but wish there was something smaller than a mini to use at the gym or something. It is extremely lightweight...I had my Mini in one hand, and the Shuffle in the other, and it was like holding a paperweight and a pen...
Definitely a good 'beginner' iPod...
