I once spent half an hour on the phone with a dialup customer who couldn't get connected. Fortunately, they fixed their own problem - they had been entering the "letter zero" instead of the "number zero" (their words.)

Took another call from an irate dialup customer who demanded a refund - he didn't know he needed a computer to use the internet -- and had driven himself mad dialing up our modem bank with his telephone and waiting for the training tones to subside so he could begin to navigate the internet as he imagined it to work: press 1 for email, 2 for news, 3 for weather...

Despite the proliferation of smart phones and greater prevalence of home networks, I don't think the situation has changed much for a segment of the population once you get down to troubleshooting why something isn't working. The skills and the willingness to just try to fix the problem aren't there.
