I have seen plenty of corporate software that was supposed to work with exactly that version of IE. When you were automatically forced to upgrade to a newer version usually nothing worked anymore. In some cases even forcing the compatibility layer. I would rather see that kind of software, developers that produced it and users disappear. In my experience few things are more annoying than an IE specific website. If you are happy with it, then great for you. But I believe that you are the first person that is actually happy to use IE given the aforementioned quirks.
