Most teenagers are tech savvy today. They are raised around computers and using mobile phones and so on.
Of course i am from the U.K so it could be different in tiny little towns in the U.S but i would not of thought so.
IMO
As I said, it is relative (I think someone else said it first). My 30 year old was raised on computers; he started at about 18 months playing games with his big brother. I think I may have said this somewhere here once before, but by the time he was about 2.5 years old if you asked him how to spell run, he'd say, "R-U-N enter!" A couple of my nieces also have kids who started around that age, although most that I know don't start until they're in school. I do know 13 year olds who barely know how to turn a computer on because they only use them in school and don't have to know much, but some of them can type a text faster on a phone than a lot of people can on a computer keyboard. I also knew one a few years ago who was amazed when the batteries went dead in his grandmother's remote and she changed the channel manually. He didn't know it could be done that way.
