"Hmm, an iPod is cool, but how cool are you when you get a phone call on your mobile phone, have to pause the iPod, rip the head phones off, answer the phone, etc. etc."
Frankly, many of us are cool enough to answer mobiles when we want to and when it is convenient to us. I get your point but, frankly, I don't think there are many adults who are that bothered.
