These programs are great for sitting down and writing with no distractions, but if you have a setup with directories full of word docs, text files, various graphics, even excel sheets all related to what you are working on that you need to refer to and cross-reference, they are less useful than an older version of Word or OpenOffice/LibreOffice. And they are difficult to export, share... there's a reason we don't use typewriters anymore, or DOS programs whose output is confined within a single program.
