What we've come to realize is that our application experience does favor Firefox and Chrome over IE. It's been a little tough to accept that internally because being browser agnostic is important but when analyzing the amount of "one-off" visual issues that are browser related, IE8 and IE9 are always at the root. So we're starting to feel comfortable recommending our users to avoid Internet Explorer all together and so far the few people we've spoken with are comfortable with that change. They just want the best user experience.
Since we so wholeheartedly believe in great a user experience, it's time to be ok with saying... the Internet is just more beautiful in Chrome or Firefox. And my personal opinion is that Chrome is really the best browser experience and I believe will continue to win out.
We won't ever abandon Internet Explorer but we recommend if you're using IE... to take a look at Chrome or Firefox. You will never look back!
