That second paragraph is a convoluted nightmare. I'm still not sure why they need administrator access on your computer, although I am sure I saw a run-on sentence.
IE6 really sucks. It's not even the features, it's buggy and slow. Although IE 8 is truly horrible with Microsoft asking questions in a different way to confuse the Hell out of everyone. Let's face it, Microsoft software sucks, always has, and when faced with competition that their established position can't overwhelm, generally fails. IE is losing market share, and mind share, and that's not a bad thing.
I'd like to see a survey that talks about why people use IE 8. IE 6 is from inertia, mostly, but IE 8? I'd be really interested in why anyone would use that. It has some nice features, but the implementation is so poor, it's almost moot.
