I had never heard of the iOS simulator! Thanks for mentioning it, it just changed my friggin life. I'm on Snow Leopard, and there is no free upgrade to Xcode 4.0. I hunted down a torrent of 4.2 and got it installed though, and the simulator is pretty great.
My larger point is that the hassle isn't supporting X version of a browser anymore, it's supporting X version of a browser on various hardware devices. Web-dev hell isn't going to be the fault of IE anymore, it's going to be the fault of mobile platforms with differing browsers, screen-sizes, and use patterns.
