If I were under 20, I'd be very upset at being caught listening to the elevator music that U2 churns out these days. I'd have to explain to my friends what it was doing on my iPhone.
Being under 50, I'd only be mildly upset.
Either way it's totally inappropriate for Apple to push unwanted content at their users.
Both my kids turned up yesterday and asked me why the hell I put U2 on their iPads.
