Perhaps so, but that does not mean that situation will last forever. Do you think the entire world will still be editing all of their documents in MS Word in 10 years time? 20 years? 50 years?

There are growing numbers of alternatives, from cloud based systems and from LibreOffice etc. Not to mention that the "word processor" itself as a category of product may become less appealing. Word Processing fit into a world where communication and documents were primarily pieces of paper sent by post and fax and this is the metaphor that it is built around. I think this is mostly still in place due to the stubbornness of the generation who are currently in charge at most companies/governments and grew up around this.

One project I will be working on in the near future is for a company who currently use Office. It will essentially be a modified Wiki that will allow them to share information & documents internally (converting existing .doc from outside sources into wiki entries will be one part of it, also automatically adding incoming emails to the wiki in some cases). It will also allow things like producing high quality PDFs for clients.

Once this is in place they will pretty much be able to uninstall their word-processors.
