Thanks -tom for pointing this out on the forum!
In yet another silent release by Apple, the U2 iPod has been rereleased. It silently appeared on Apple's site today, with the slogan "Back for an encore". It features video, color screen, and engraved autographs on the back from the members of U2.
However, one has to wonder if there will ever be an Apple announcement again, between the recent Mac@work section appearing on their website yesterday, the much anticipated Macbook quietly appearing, and this. Maybe it just means they have a big announcement coming up.
