Not exactly. If you target designers and developers, you'll have much lower IE6 market share. If you target enterprise users trapped by a fearful and incompetent IT department, it'll be much higher.
In near future, after IE9 has been launched, every major browser has (sort of) CSS3/HTML5 support. To prevent IE7 & IE8 becoming the new "IE6" for the next half decade, it's important to let them die. As a web developer, prefer graceful degration over pixel perfection. Let everybody access the content, but require a modern browser for eye-candy. People will upgrade (even corporations!), if they were not given another option.
IE6 usage is now below 5%? Wow, it's so cool to be part of such an exclusive club. Thanks Boss for keeping our organization on the bleeding (trailing) edge.
Depending on the kind of website you are making, you could ditch Internet Explorer 6 a long time ago.<p>Only three percent of all visitors used IE 6 when visiting a website for a academic conference (social science, German speaking countries) I made. Also, Firefox was nearly three times as popular as all versions of Internet Explorer combined. And that data is now already half a year old.
Wow, a site with “Ajax” in its name that, <i>on load</i>, presents the user with a confirm() dialog that redirects them to the Flash install page? — while there is an unpatched critical zero-day bug being exploited in the wild? There is a reason I have Flash disabled!<p>(Also: My site, which is geared toward OS X users and web developers, has 2% IE6 traffic.)
On a commerce website I help with, 6% of the visits in the last 30 days are IE6, which is 7% of the revenue. Those numbers are about 50% of what they were during the same period last year.<p>As an interesting note, the site still has a user on IE5.01 that orders every few months.
My wife works at some huge company, and is so forced to use IE6. Apparently Google Maps and many other useful websites don't work anymore and crash the browser (No, I didn't care enough to check :). So yes, the end really is near.
