It’s compatible with 30GB, 60GB and 80GB iPods, and promises a battery life of up to eight hours watching TV shows, music videos, podcasts and films from your iPod. It also acts as a hard case for your iPod, and even comes with a car adapter. I don’t think you’re supposed to use it while driving, mind.
myvu costs just under $300 in the US, although no news on whether it’ll come to the UK, I’m afraid. I can tell you that it works well, with fairly comfortable earphones. I’d still feel a bit self-conscious wearing it in public, though. But if you’re keen to surf the futuristic video wave (i.e. you don’t mind looking like a Star Trek extra), it’s cool.
