I watch the pre-game show on HDTV… Walking to the stadium, my excitement builds as the experience follows me on my phone … In the stadium, I see a great run and get statistics on the running back... Of course, I order clips of Purdue’s win over Ohio State in the final 10 seconds … They’re available anytime … When I’m with friends in the Union … When I’d rather see a curl on a football field than an H-field.”

11. 11 “I like to share music videos with my friends. My PC’s big screen really makes the latest John Mayer MV come alive in my room … My friends call, so I pause it and get ready to meet them at Starbucks … I resume the MV on my phone while on the walk there … Sipping Cappuccinos, we take turns sharing our favorite MVs on each others phones … Sharing with my friends is cool; I even share some clips of John Mayer I took with my phone at his last concert.”
