I miss the ¢ key too. I usually have a couple of occasions a week to use it. It's a pain to have to go through extra steps to get it when it should just be on the keyboard. Same for the ° (as in 98.6°).

You'd think that with all the "alt", "shift", "ctrl" etc. keys on a keyboard they could come up with a way to have another row of characters. For US users I would vote for ¢ ° ™ £ © ® ± ¶ ¼ ½ ¾ ñ.
