I, for one, liked clippy (in his wizard form), as did the rest of kids in the computer lab, if anything the best feature of clippy was that it kept kids focused on the computer (but I guess not on their work)
Are you sure about that? My recollection is mostly clippy doing inane animations in the bottom right, with no real good way to turn him off. You could tell him to go away but by default he'd pop back in real quick as soon as he thought you were doing something he could help with. Even the more permanent setting to turn him off would periodically revert.
It is such a mystery. It _should_ be great, it should be helpful, but it's not. Whenever you ask it something useful, it responds that it can't help you with that.
