I did a fourth-month project in LA recently where we had to support IE6. After that experience, I have decided that I will not, ever again, support IE6 in any way, shape or form. In fact, I won't be supporting ANY version of Internet Explorer. If my code works in it, great. But I'm not going out of my way to make it work if it doesn't, when it works fine in FF, Chrome, Safari, etc.
I currently run a few web message forums on code I wrote myself, dating back to 2003. I'm in the (slow) process of rewriting it to Web 2.0 standards, and I've already announced that IE will not be supported in the new version. Most of my users have wholeheartedly agreed, fortunately.
Since Yahoo and Google dumped IE6 support, it's a good first step at ridding the 'net of that monstrosity.
I can't even begin to tell you about my complete and utter HATRED of Microsoft and their thinly-veiled attempts at strong-arming the Internet into their way of doing things. I switched to the Mac after my fresh new Windows 7 install bluescreened on me five times in a month and a half, the last one causing me to have to reinstall the OS. Then it bluescreened two more times soonafter, and that was enough to make me move.
