Reasonable. I work in a big enterprise, they upgraded to Office 2010 from Office 2000...

The cost of retraining is what gets many businesses.

That's a joke I don't know anyone who has EVER had an training from their employer regarding these products which probably explains why the get so badly (ab)used. A word processor is a word processor (& the same for spread sheet) once you know the basic principles it is a simple matter of locating the option req. in them menu's moving from one to another should not cause difficulty to any one with an approximately average IQ.

The only thing that keeps Office going is momentum & upgrades are forced by Microsoft changing their format just enough to make files incompatible with older versions.

..and that (used to) show in spades.

I remember seeing docs produced, by paid staff in offices no less, who clearly didn't know about setting page margins or paragraph formatting. This was with Word too. Once I had to sort out some document which was a misformatted mess. Setting Word to show tabs and newlines showed that its author always used tabs to indent the left margin and then, at end of line, set the right margin by tabbing to the start of the next line and indent it, ending the paragraph with a double newline to leave whitespace before the next paragraph. Needless to say, there wasn't a style in sight.

This was back in the days of Word For Windows 1 or 2, but I do wonder how often you still see untrained users doing this sort of thing.

A trained typist by the sound of it.

I doubt it - trained typists are an endangered species.

A typist trained 30 years ago. I learned to type on a mechanical machine. I still double space between sentences, but most of the software I use takes out the extra one. lol I'm happy to trade that for getting a spell checker! :)

No typist (or anyone else) was trained to "set the right margin by tabbing to the start of the next line" - you just CR and tab.

I learned at high school, on IBM Selectrics. Oddly I've unlearned most of it since - perhaps because the special characters commonly used in programming didn't occur in the "quick brown fox" exercises.
