My problems with my iPods are battery based for the 6GB and 20GB ones.
And also my 2nd 6GB one randomly paused. The stupid guy at Apple said "that's the first I've heard of it". I told him "Maybe you should add it to your list of Apple problems because it is definitely a problem". And eventually it ended up being a common problem with the iPods. Typical when I was trying to show him, it wouldn't happen. So I demanded this was the 2nd time I've taken my iPod for problems, and I said "I am not moving until I get another iPod out of the box". He was going to send it to Apple after 3 days.....stupid dweeb. He got a new iPod, slammed it on the table and walked off. I was happy
Also Null....with the up and down, you can hold it down, so you don't have to keep making circles with your thumb. It's so much easier imo. It will go through the list very quickly. But it's up 2 u which u prefer obviously.
From all of this, I'm never buying another apple based mp3 player. I think they are way overrated, and there are much better quality players out there.
