Interwhat?? Do you know people that have no idea what Internet is?

Seventy three percent of the Dutch are on Internet on a daily basis.
And I believe 90% of households are connected to it.
That leaves quite a big bunch of people that are not on daily and also about ten percent that has no Internet at all.
A colleague sixty-ish years of age of mine, today while we were having lunch, appeared to be pretty surprised to hear that you can listen online radio on the computer—he has Internet since some months and is learning how to use it (and the computer).
His reaction amazed me.
Do you have people in your social environment that are oblivious to the fact that there is such thing as Internet?
