I see on the BBC news today, that micrsoft have baked a cake to mark the end of Internet Explorer 6.

We've been encouraging clients to use alternative browsers for the last few years, however the corporate world has been slow to change.
Many organisations still run IE6, due to due to the legacy applications they still run that don't work in newer versions of IE. The cost to upgrade these applications has so far been too great, without a valid business argument to back up the need. Can you imagine putting a proposal to the board, for an £x million pound project to upgrade your ERP application, with the justification being to upgrade Internet Explorer!? Now I know there are other benefits to upgrading, but it’s not a decision taken lightly, nor performed overnight.
We've found many corporate users now running Firefox or Google Chrome for web browsing and using IE6 for internal apps. We stopped catering for IE in our applications, and have simply added a warning now to advise users to use an alternative browser before they login.
I can't see the corporate world jumping ship anytime soon..
