The fact of the matter is that documents, spreadsheets & presentations should be able to be created seamlessly by all staff!
There is nothing wrong with using police, nurses, teachers, stockbrokers & so on when benchmarking office suites.
It should not require an IT degree just to use an Office Productivity suite.
The whole point is so you can look at non-IT literate demographics (ie: regular people) and see which they prefer so as to figure out which is cheaper to support over the life of the product (and yes, open-source apps get EoL'd far more frequently than closed-source proprietary software).
Ideally everyone, especially teachers, would accept PDF as a printable and 'portable document format' (funny that). Since it is so close to PostScript. (This way documents that do not require edits after final publication could be opened by all and would view the same on all platforms, including printers!).
It doesn't take a genius to figure that much out.
