in my experience
I bought a new iPod the night they were released, and I think I was the first one to complete a sale at the Tyson's Corner Apple Store that night. Some tall Apple nerd with a camera saw fit to document the event on a silver substrate, so I'm guessing the guy next to me at the other register came in second.
Regardless of who won (me) a new personal habit has formed as a result of iPod ownership. I actively try to wear shirts that have a breast pocket. This is of course for the iPod to have a place to perch while I walk around the office with my headphones blaring Phasmid. Unfortunately, the iPod really is just another gadget that I carry around with me every day, and it's getting ridiculous...
