Average student is using Google Docs and Drive but the office workers I hear are driven by corporate culture, and traditional places of work like accounting offices haven’t culturally embraced these kinds of solutions.
Google docs is absolutely inferior in its power, formatting options, display performance, ability to write mathematical equations and diagrams directly into the document, etc.
Every time I had to produce a non-trivial report in google docs I grind my teeth and end up rendering these things elsewhere and insert them as png.
Additionally, google docs gives you no ownership over the software or the files I find it's commercial model unsettling.
