Likewise. And it's the only way to get decent typesetting on complex equations for one - though it might be a mistake to include those on many posters.
In my lab most of the poster templates were already fairly standard and available on a shared drive. Also anecdotally, I stopped sending my professor LaTeX documents as soon as she said she didn't know how to open them/wouldn't be bothered. It was a point of pride for some professors to use LaTeX, but we generally used word for the edit tracking feature to publish efficiently.
