What version of Office are you using and supporting?

Are you still supporting Office 2003 or an even earlier version or has your organization moved on to 2007 or 2010?

It's been a while since our last poll regarding versions. I don't want to limit you to a single response, so this time… no poll. I'd like to know which version(s) of Office you're currently using and supporting and if you plan to upgrade to 2010. For the most part, I still have few clients using 2007, let alone 2010. The network of consultants I work with report the same thing -- they are still supporting 2003 more than any other version. A few are still supporting Office 97 applications! So how do 2007 and 2010 fit into your organization's scheme?
