Five months ago I was in the camp of "All I need my cell phone to do is make and take calls." Then I realized that sooner or later I was going to need to design user experiences for smart phones and that I had no direct experience as a user. So I cowboyed up and bought an iPhone.
Fast forward to yesterday. I got a call from our customer loyalty manager late in the afternoon (on my iPhone). We are doing a big customer hoo-hah thing today and we were out of Post-it flip charts. (Who you gonna call? Apparently the UX guy!)
So I go down to the conference room to see what they need. They showed me what they had and suggested I write down the part number and description. "Not necessary," I said. I took out my iPhone and opened my RedLaser app. I scanned the bar code and got a description and the pricing for all the local office supply stores. I put the address of the closest Office Depot in my Google Map app and used my iPhone's GPS to get there.
When did I become "that guy?" Five months ago I'm all about "I don't need no stinkin' camera in my cell phone," and yesterday I'm laser scanning bar codes with it.
Lesson for UX: Discount NO technology. The adoption rate happens in dog years, if not faster.
