And then spend twice the time formatting equations correctly and dealing with things that require workarounds because Word only handles a tiny subset of what LaTeX and LaTeX packages can do? No thanks.
Even if you don't want to do it personally, you can ask the maintainer of the relevant package to add a certain feature and if you're lucky he agrees and does it, or you can pay someone to do it.
It's easy to forget, but you do have the total freedom to make it work for you, unlike proprietary office programs.
