I had to support a really old site that another developer wrote on IE just over a year ago. Luckily I am no longer at that company. Basically 99% of development and sites worked with modern browsers but one needed site required IE6 compat mode. It would have taken months to rewrite and the company didn't want to spend resources on it. At my current job we also have a lot of IBM software that seems to work best in IE although only a few people still use it at work. Doesn't seem like IE will be retiring anytime soon. The article (and site) from this post is very good.
