There's nothing to be sad about, it's a decision we make everyday. If IE is so painful that the revenue is not worth it, then don't do it. We currently don't support OS X. I'm not sad when Apple ships a new version of OS X. I just know that the 10% of the market that they own is one that we won't support. I'm fine with that, and have been for a while now.
"Well, sir (or ma'am), your new website will only work with 'Modern' browsers."
"I see. And what is a 'Modern' browser?"
"Anything but IE."
"Ah. Nice meeting with you. I'll keep your quote in mind."
No IE support != less revenue. No IE support = no revenue.
Our day is coming...
I'm afraid our problems with IE involves other people using it, and their choice to do so is largely beyond our control.
