Just headed over to StatCounter to check the latest browser stats.
As I write this IE6 has had an average of 13.7% market share for the past year *puts head in hands*, on the upside the market share in Europe went under 5% in Europe and under 6% for North America for May 2010.
I also read an article containing an interview with Ryan Gavin, head of the Internet Explorer business group, who is quoted as saying:
Part of my job is to get IE6 share down to zero as soon as possible
I hope he is VERY good at his job.
Update 4/6/2010: Really? IE9 100% Compatible with HTML5?
