Hi, I'm writing this thread because I'm strongly considering purchasing an iPod Shuffle for use when running or at the gym. I've never owned a shuffle, and now with the release of the third generation I'm thinking that it's a good time to make a purchase. The "dilemma" I face here is: Do I buy the new 3rd generation 4 GB iPod shuffle, or do I take advantage of the previous generation shuffle because of the price and availability? To be honest, money really isn't the biggest issue...I guess I'm more or less looking for advice on which iPod is the best of the two as far as performance and functionality. I appreciate any insight the MacRumors community has to offer, and welcome any reviews/testimonials people may offer that own either, or both versions of the shuffle. Thanks!
