Classic use while exercising?

I don't have a classic, but from what I've read on the subject, it's not a big deal if you're not in constant motion for more than 20 minutes at a time. So if you are a serious runner and are regularly running more than 20 minutes, it's a problem.

If you're just at the health club moving from machine to machine, not so much of a problem.

That said, I love my nano for running. I run about 50 minutes a day and it's just great for that. I think something as bulky as a classic, even if it could handle the jiggling around, would be annoying to carry for that distance.

 

I have a third generation iPod (2003) -- and it would lock up periodically, or skip when I ran

weight training, or cycling suffered no issues

 

I've never had a problem running with mine.

 

cause you're not running fast enough -- i kid i kid

or you simply glide along and run with the softness of a gazelle -- haha

 

I've been mountain biking with my 5g for a very long time now with no problems.

 

The HDD only spins up when it needs to get songs; just make sure you have a playlist set up, that way it will spin up, fill the cache with a bunch of upcoming songs and be done with it. The cache is around 64MB, so that's enough for 10 songs assuming they are not lossless or something like that. So it will spin up after those 10 songs and refill the cache again; you should have no issues; if you are really worried, spend the $50 and get a Shuffle.
