As someone who's been doing web development since 1995, I have wasted an enormous amount of my life dealing with IE-specific bugs. This is enough for me to feel uncomfortable even thinking about Internet Explorer and has tainted me against Microsoft products in general...
When our company decided to stop supporting IE.. I had the best day of my life at work yanking out all of the 'kind of' working IE quickfixes/hacks we had used out of the source code. I couldn't agree more.
Do you remember NS 4.x and JSSS/translated CSS at all? I do. IE was many, many times better and easier to develop for. (And, frankly, their box model, equivalent to border-box, was the right way to go.)
