I'll say it: the iPhone is the new Millenium's version of the charm bracelet.
As a child of the 80's, I had a charm bracelet. Granted, it was a cheap one, plastic and pink, with clip on charms. But boy, how I loved it!
And as I see more and more iPhones-okay, I'll 'fess up. I was watching 30 Rock and Danny was showing Liz the iPhone app where it sounds like an empty can when you shake the phone and I realized we have now entered the new version of the charm bracelet. Except for 10 or 20 charms, this one has 300,000. Wow!
