While the group continues its world tour at the moment, U2 is considering releasing their album via Blackberry. It’s being described as the U2 mobile album, which is a great idea. How many people are going around with their Blackberrys at all times? They could listen to U2 at their leisure, on trains or while on the go. They can also play it for other people. But I’m having trouble telling what makes that different from using an IPod or some other kind of mobile music device. A mobile album doesn’t seem like a new idea, so maybe someone can set me straight on this?
