U2 sell out

What is it with U2 and advertising. I could forgive them the ipod advert - after all ipods are quite cool and Vertigo is an extremely catchy song but the Blackberry advert is just taking things a bit too far. What was Bono thinking - record and ticket sales are low I know lets do another advert? Well I've got one word for you Bono (well two with a hyphen) - sell-out!
