There is a lot of talk around the interweb these days about IE6 and it's impending doom, as worldwide stats show it's decrease in usage. The trouble with the various statistics though is, which ones are accurate? What can be believed?
Browser Usage differences seen
I have seen Browser Usage Statistics from various "reliable" sources (I don't know how to tell the difference between reliable and unreliable, but pretty sure Dilbert's rubbish collector was one of the sources) that show IE6 usage as low as 1.78% worldwide amongst Internet users, and as high as 7.7%.
