It was originally a textarea, but I changed it to an input box because:
* That way you don't have to move your eyes up and down a large distance back and forth
* A textarea on the longer lessons might not fit on lower resolution screens, and text-based browsers (users which are more likely to be unable to use TypeFaster or KTouch).
* Since textarea's aren't exactly in the same dimensions/font of the text, the text is going to wrap in different points of the line, unless you press Enter after every line, and it's better not to. Pressing Enter means either stretching the pinky or moving from the home position.
