Define valid. The reason in the giant organization that I work in is broken internal applications. The number of internally deployed web apps that were targetted for IE6 and nothing else is truly astonishing. And the speed with which they get updated is astonishing as well. We finally deployed IE8 this year after almost 2 years of remediation effort. Which just kills me. (And of course because of thinking about security harkens back to the 1960s, we are a full year into exploring the deployment of Chrome or Firefox as a supplemental browser, but at present it is too risky)
