Luddite friends (who won't read this obviously)

Do all of your friends have a computer? These days that would seem to be a ridiculous question. Everyone has a computer. And an iPhone. And exact knowledge of Wi-Fi spots and internet cafés for every journey.  27/7 access to Twitter basically. 'Tis the modern world. 

So I consider myself to be quite unusual in that the vast majority of my friends are barely techno-literate. Of my three best friends, I have an email address for one of them. One doesn't even own a computer. 

This would be the perfect place to slag them off of course but I actually like them - more's the pity. But I wondered whether this was as unusual as it seems? Or am I just buying into a media construct of what the modern person is, does and has these days?
