I've always had a bad attention span.

Hi-def is merely the latest in a string of evolutional leaps that have transformed the way we sit slumped in front of a box wishing we were dead.

When I was a chain smoker, I used to wake up and the first thing I'd do was reach for a cigarette, basically. And now I do the same thing for a smartphone, basically.

Our four-year-old, like a lot of kids, you introduce him to an iPad and he quite quickly gets drawn in in a way that you're like, "Wow, I've got to stage an intervention here."
