but to the average person they put a document on a scanner (or scan it from a computer document) export it as a pdf and add it as an "attachment" in or after a document. fast, simple, easy, but not very accessible. got a full time IT dept yes it can be done but it is still not intuitive to the common user. who more and more is not within the business/education community. in a couple minutes I can take pretty much anything, scan it on a $100 flatbed scanner, then send the result as an exported pdf document anywhere on the web. or even worse send a scanned text document as a jpg. but we are not talking about that.
