Tweetgotta get a nano man. Like the dude said earlier Best Buy is great for the warranty, and If you love music and have lots the nano can get you 2-8 gigs depending on how much money you have. Nano is way better for resisstance training (wont get in your way not to bulky almost as small as a shuffle) but for cardio nothing beats the video Ipod. Just download a season of your fav show and youve got (20+) 45 min sessions of blissful distraction filled cardio!
