The install base of IE6 users mostly will be the people on pirated copies of windows that can't get updates anymore. I suspect that if you matched up the browser type and country of origin, you would see that your IE6 users are mostly in asia and third world countries at this point. Your actual install base in the US and Europe would be very low at this point, as Microslop is pushing out IE8 pretty hard now (in their regular security update packages).

Windows7 is a game changer here, it is the operating system that Vista should have been, and will likely lead to widespread upgrading and updating. The price point is excellent, and it really does seem to work well. The low prices for computer hardware at this point is also a good indicator that christmas 2009 might be the year of the "big computer upgrade" for many households.
