[eli]

I've seen some numbers that are nearly all business users. They've actually improved considerably in the last year or two. IE6 was quite common in certain sectors like government, finance, healthcare, (see if you can guess what those industries have in common) but in late 2010 and early 2011 people finally really started upgrading either to newer versions of IE or, surprisingly, Firefox.

IE6 use (even among business) is extremely rare right now. Which makes sense, because very few websites would actually work.
