The web developers of the world will rejoice when we can finally retire our IE6 tools and hacks, but this doesn't seem a likely solution. I've found that most people still using IE6 are either older and don't care about upgrading or are in a business environment that forces them to use IE6.
As far as I'm concerned Microsoft should issue a force update to all IE6 users that will push them to at least 7.
At the moment I am in an office where some essential software won't work on later versions of IE while IE8 is a pre-requisite for other essential software. I think my boss had the right idea and found a new job a couple of weeks ago.
