Did it ever occur to you people that some people use neither IE6 OR IE7?
As the above poster said, whether or not you use it is completely irrelevant. If you have Windows, you have it. If you have Windows and IE6, you're shooting yourself in the foot because IE6 is notorious for security issues. Whether you're on Firefox or Opera or Chrome or whatever, you should update to IE7.
Your argument is like complaining that you bought a car but can't go anywhere because it needs gas. It's not like the IE7 requirement is some fishy archaic software that you don't know where it's been. You don't have to like it (people certainly don't like paying for gas
) but it's integrated into Windows, so it's there.
If your hatred for MS and IE goes as far as willingly leave your computer with more vulnerabilities and pass up on great games, well, that's your choice
