Paper is just a medium for information to exist. The medium doesn't need to be replaced. It should be bypassed. I think it's a habitual crutch workers have, to print information out, for it to be tangible.
I agree that although horribly inefficient, paper is cheap (even with printing expenses), and thus attractive compared to buying everyone an iPad. That's unfortunate because I believe it handicaps workers by acting as an unnecessary bottleneck when it should be completely removed from the information workflow wherever possible.
