There's a lot to be said for wysiwyg. Most people are unwilling or unable to learn or use formatting code in plain text and no immediate rendering of the result.
But fundamentally there's no reason why anyone should have to deal with plain text source that produces nicely rendered output (unless we want to). Computers are really, really good at displaying things nicely, and hiding details.
The problem is that Word (and the creeping Sharepoint ecosystem) are much too powerful for almost everyone's needs. My work is typical: all our documents are a single font, and they have tables. The docs are kept in Sharepoint, and we do nothing with Sharepoint but keep documents.
That over-engineered solution would be better replaced with a very simple word processor like WordPad or some similar rtf tool, and the file system.
I don't need to use the truck that takes space shuttles from the vehicle assembly building to the launch pad just to get to work.
