Steve,
Personally, I think for everyday letters, ad-hoc reports, informal
reports,
initial design documents, and general "stuff" that's not too
important,
That's worth thinking about.
For formal reports that have to look good, and especially if they
have to look
consistent with former reports, I'd go with LyX over Word.
This is what I am mainly interested in, having experienced how much
better a report looks produced in Lyx is compared to Word, its the
production of technical reports that I can see the biggest advantage.
But I admit, I had been thinking of trying to move everything over to
Lyx, as Rich has now done.
