In my unstudied and ill-informed opinion, computers and the internet have trained many of us to view intellectual content as more abstracted from the physical experience of ingesting it than it really is, as though the ideal of reading would actually be telepathy from writer to reader, and anything added to that signal chain must be by definition noise. I don't know if I totally buy that view though. I sympathize with the students who focus better with print; I do too - and I take better notes when I write by hand. I don't think that's because I'm anachronistic; I think it's because of some fundamental aspect of being both a mind and a body.
