I don´t own any Britney Spears products either and still these worthless things sell millions and make people "happy", but are they truly happy? Or is it just materialistic behaviour and need to fill their empty lives? Yes, just like with iPad.
The iPhone is also materialistic crap. It doesn't add anything to your life that could not be achieved with simpler things. If you needed a phone you can get them for $20 at a post office.
Preference in music is entirely personal. Please list your favorite artists and I will rag on them. After all, if one person doesn't like it, then all of the other people are unhappy materialistic empty lived suckers.
