That does seem to be the way computer screens do seem to affect an awful lot of people, leeneia. It's a bit depressing in it's implications for our future.

But another way of seeing it is that maybe that's possibly a guarantee that physical books won'r ever be completely displaced by ebooks.

But I have a horrible feeling that won't happen with print journalism and that printed newspapers may vanish. TV news and online media are no kind of substitute for that.
