uh huh. i agree, apple should replace the batteries free of charge (something no company in the entire world does) until they're completely bankrupt. then we won't have to worry about it at all anymore.
i'm sorry, but no rechargable battery lasts forever, they all have a certain number of discharges before the chemicals wear out. the only problem is that the iPod is a closed unit, so batteries don't just pop out like they do on camcorders. but honestly, the closed system is part of what makes the iPod such a great player-- you don't have to worry about grabbing extra batteries for a trip, making sure they're all charged. they gave us a single battery with a very long charge (at the time when they created it, this battery was pretty revolutionary) in a small package.
500 charges should last the average person (which is who Apple designed the ipod for) between 3-5 years. i'd say that's not terrible. yes, this is a bit annoying, but it's not something i think people need to go defacing their ads over... if you don't like it, go find an MP3 player that runs on AAs, see how much *that* costs you in the long run.
