Robert Scoble has a nifty little photostream available on his Flickr gallery, called iCult. In it he profiles various well known bloggers, tech celebrities, and other digerati who proudly carry iPhones. All the A-list people are there including Chris Pirrilo (pictured above) wearing his usual "Feel free to punch me in the face and steal my lunch money" geek persona non grata.
I see lots of tech workers inside major Silicon Valley's companies carrying iPhones these days. Google, FaceBook, Flickr, Yahoo, the usual suspects. Even Microsoft employees use them fondly, with cautious restraint.
