I am comfortable enough with latex that I often work through problems on latex. For certain cases, with long expressions, it is actually simpler than handwriting, because I can copy an equation onto the next line and edit it in-place, hence, taking less time and ensuring I am not missing terms. I have a friend who got so into latex that a few times he would mindlessly use latex code while handwriting things, like writing "\alpha" on the board instead of drawing the greek alphabet.
