Unfortunately a lot of users are already adopting alternate browsers, but it doesn't reduce the pain of web development until IE6 becomes a negligible part of the market. What could help more than anything is if Microsoft took a stronger stance on forcing users to upgrade from IE6 to IE7. Once IE6 drops below perhaps 5-10% of the market it becomes ignorable. But for IE as a whole to become negligible - I wish I could but I don't see that day any time soon.
