Redmond would love for everyone to believe that, but the fact is that IT isn't ruled by them or anyone else. Most of the problems that result from IE are due to the fact that they believe their own hype, and feel perfectly free to ignore the standards that they've had a hand in developing whenever they get the urge. If it's important that a web site I develop be accessible for viewers, I have to accept the fact that people will be using IE, Firefox, Opera, and some other browsers, and working on Windows, Macs, and Linux. That means either a lot of plain vanilla, combined with multiple versions or pages and some alternate code paths. BTW, I just tried it with IE7 and was presented with the full-width text window for comments.
