I loved clippy, and found it super helpful. Granted, I was a child and fascinated with the idea of artificial intelligence, which clippy was the closest thing to at that point in time. It was a useful tool, and it's at times irrelevant suggestions got me exploring things I would never have learned through school or casual exposure. All in all it was a fun, quirky, at times useful and all around great tool, just not for the target audience.
