I actually disagree. The equation editor in word is really quite good (if a little laggy sometimes), once you learn the shortcuts. Being able to see your fractions laid out properly is a massive productivity boost, and makes it much easier to quickly find the part you want to edit. The dealbreaker for me is the lack of equation numbering, without doing quite a few hacks.

Personally, I'd still take the LyX math editor over Word though, for the macros and better performance.
