Well, I have had my iPod for about a year now (I got it last Christmas), and so I guess that I have six more months until I have to get a new battery (because after 18 months, the battery apparently dies). Of course, if you do not know what I am talking about, go to this website now.

"iPOD'S UNREPLACEABLE BATTERY LASTS ONLY 18 MONTHS."

P.S.: According to an article about this in the Washington Post, Apple, because of this issue (see the site above), has now announced that it will sell replacement batteries for $99.
