I've actually never had much of an issue with Internet Explorer, but I do hate supporting it due to the vulnerabilities it had in the past. I recommended Firefox/Chrome to everyone just to avoid ActiveX for those that don't need it.
I've always been a little curious as to why Microsoft cares if people use their built-in browser or not. Do they get some sort of income from it?
The Dalai Lama, when asked what surprised him most about humanity, answered, “Man. Because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present; the result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived.”
