[quote name='jerfgoke']Basically what the post above says. Running, or any activity that subjects a hard drive to bumps increases the wear-and-tear on the moving parts of the drive. I'm assuming this is why Apple doesn't sell the Nike+ running kit for the video iPods. The flash-based Nano doesn't have moving parts, and won't have this problem.
That said, if you're already running with the iPod, I wouldn't bother changing anything. I see many people running with them on campus here. But if you're looking for a new one, it's one more thing to consider if running is your main use.[/QUOTE]
Okay, thats what I figured.
But you'd think that Apple would have thought that people would use these with exercizing, which would explain why exercizing with them would shorten life span, meaning you'd have to buy another... Damn them, thats clever. Oh well, I've been using mine with my running and weight lifting for at least 6 months, and I'm not about to stop. I guess I'll just grab an armband or something.
