So yeah, there are a few things left in this world that get me in a bad mood...
Professors who speak down to me in condesending tones and pretend to be friendly when actually being bastards are one of them

I had one of those last semester. This semester, I sort of have one.

I admit, the keyboard on my laptop is loud, and I type VERY quickly, so its a constant sound, especially when I am taking notes. And I admit, allot of times I'm doing more than JUST taking notes. But neither of those reasons are enough to very subtly sugest that I shouldnt use a laptop in class at all. I would understand it if some other student had complained to me - I've had that happen before, and usually between the two of us, one of us will move, relocate, or otherwise make the situation tollerable. I would even understand if other students had complained to him, and he told me that. But I think he finds it annoying that I sit and type during class discussions, occasionally looking up and saying things in the discussion, or making comments on the presentations, or what ever I'm expected to do. And another thing - if you are planning to enter a business enviroment, you better be damned well prepaired to deal with less than perfect speaking conditions - especially with the sound of a keyboard going while you are speaking. There are these little things called meeting minutes that are now almost always taken on laptops or desktops or hell even PDA's.

And that he threatened my participation grade when I was fairly sure I had been more than vocal in the class... thats very uncalled for.

Maybe I am just being pissy. Really, I'm just trying to slog through that class, no matter how nice the professor is, it doesnt make the subject any less unplesant, and me any more comfortable with public speaking.
