The point I'm trying to make is that going from zero to hero, even with basically "infinite" money like Google has is very very very hard.
The tricky part is how many organizations have an enormous amount of business logic programmed into excel sheets.
The Engineers: Word processor with basic features is fine
Management and Execs: Comments, Review, Multi-user editing, History, Tables, change tracking.
Marketing: Image placement and alignment, layers, embedding, templates, shapes
Research/Doc Writers: Table of contents, page numbering, cross-referencing, formula insertion, citations, figure tables, export to pdf
All customers (at some point): Layout, margins, padding, spellcheck
As engineers we tend to think "just deliver a simple word processor". For who?
