The problem for corporate environments is that they tend to have a few really big legacy applications which only function correctly in older versions of IE. The question then becomes whether to upgrade the application (with a massive price tag), or keep their old version of IE as the standard (which appears to cost nothing). In fact, there are costs of maintenance and security, but those aren't readily apparent on the balance sheets.
