> People needing to do "serious" work mostly don't use MS Word in any case due to its abysmal styling and layout controls.
I keep hearing this, but that might only be true in your world. You'd be surprised how many e.g. academic journals in the social and management sciences accept *only* .doc[x] for submissions, for instance. (where often the backoffice converts the files to latex files as part of the typesetting).
But then, you'd probably not consider that as "serious work", so I'll stop here :-).
