The question has been raised as to why support IE6?

I can give you two reasons, why your client will require IE6 to be supported:

• While IE6 continues to have above a certain of browsers in use
• The web application is for a controlled environment that has not been upgraded from IE6 to a later version

I personally only use any current or previous version of IE to:

• To access the Windows Update site
• As required to test IE compatibility of applications that I write

I agree that that the CSS fixes required to support IE6 are undesirable in that they require non-standards compliant CSS. I prefer that my HTML be both XHTML and CSS standards complaint according to the W3C tests.

IE9 promises to be not only standards compliant but much better in performance. I am looking forward to its release.
