what? I've know that forever, and I don't even write or like TeX very much.
(A lot of it has to do with the Computer Modern typeface, which I used to hate, but now just find kind of bland.)
(TeX implementations that use OpenType are good, however. If I were to use TeX, it'd be an OpenType implementation with Cambria Math if that's possible.)
(I do use TeX from time to time for various purposes, such as converting Docbook to PDF)
