Apple has quietly updated its U2-edition iPod to match the specification of the 5.5G model it announced earlier this month. As before, the 30GB machine sports a red Clickwheel and comes with the band members' signatures laser-etched on the back, but now its battery life stretches to 14 hours for music, 3.5 hours for video. The screen's a lot brighter too. But at $279 - down from $329 - it's $30 more than the regular 30GB iPod, though the price includes 30 minutes' of free iPod music videos. ®
