But I found that once I learned the LaTeX syntax, I can type equations faster than I can write them by hand, especially if they're complex. This is because most equations have lots of repeated elements (for example, when say, you're rearranging an equation), and I can copy and paste faster than I can rewrite them. I could take notes in LaTeX faster than a professor could write them on the chalk board. I wrote my dissertation in LaTeX, and while I hate the debugging (errors are arcane), learning the "incantations" are really the least of one's worries. I wouldn't be put off by that.
