As a side note, a couple "shit" AA rechargeable batteries can be replaced for under $5 at the local electronics store (or any store for that matter). So even if they burnt in a year, that would not be an issue. And the other MP3 player companies would not benefit in any way from that. Aside from the point, not many MP3 players use AA rechargeables anymore.
Also, do you really think that five people would file lawsuits against Apple if they're problem was merely "blown out of proportion"? I'm an attorney and I certainly can guarantee that its usually a lot more trouble than its worth.
Please, all I'm asking is everyone consider the facts before they buy. Know what you're buying. That's the reason why you're reading the posts on this board to begin with, so don't let it end here.
Thanks.
