Sir Arthur C. Clarke, on the ‘digital-divide’:
“When printing was invented, somebody said this is very interesting but what good is it when nobody can read?”
And yet-to-be-knighted Steve Jobs on tablet PC’s and the non-demise of the keyboard:
” There are no plans to make a tablet. It turns out people want keyboards. When Apple first started out, People couldn’t type. We realized: Death would eventually take care of this.”

It’s a bit of an oversimplification to talk in terms of haves and have nots. Virtually any technology exhibits increasing returns with use, so there’s a whole raft of dynamic effects to be accounted for. The more we browse the internet, the more effective we become at getting the information/effect we want, and so on.
However, this means it’s a serious problem when people encounter barriers to achieving the “learning by doing” effects. Many of us find it relatively easy to get past these, but there are millions effectively trapped because software/hardware is not usable enough that they can begin to learn. Usability is far more important than mere availability for any technology.
Death will also take care of those users who don’t understand the file system too.
I need a keyboard because I can’t write fast enough otherwise, much less read my own handwriting.
