I would do something like that; in fact, I was thinking of doing a e-book about switching to a paperless office; and I would make a section of that (Throw out that Dot-Matrix printer) free!
I am actually in the process of doing this in my JOB, so I can give viewers a real, honest insight of actually changing this process. Not sure whether to give away my hard work for free, though; or charge a small fee.
