I think there are quite a few users who need a local Office package storing files on their computer. Shonky internet connections, local distribution of templates, control over documents &c.

I agree this may be a shrinking number of people, aligned with the PC/Laptop numbers I imagine.

LaTeX is great, but the skill set required in use is high. I find sending people a document in LO/oOo is easier for them to change &c.
