Query: Don't jog with this one

Just like Mark (posting April 5, 2006), I charged the thing up, filled it full of great music, and went out for my usual run. It worked for about a half-hour and then died. Tried everything to get it going again but nothing. Am taking it to the Apple store at the local mall to see if they have any suggestions. Hopefully, I can send it back to Amazon and get my money returned. Sigh!
