Actually, from what I've read on the CSS lists, IE on the Mac has been one of the most CSS standards compliant browsers around. Unfortunately, none are perfect, and Safari has many known problems, also (it doesn't handle nested DIV's well).
I'd say the best way to 'handle' the problem is to keep demanding that WC3 demand cross-browser standards. Don't forget that browsers are not just for computers anymore, some people actually expect to be able to 'browse' on a cell phone screen!
So, standards absolutely must ke created and used. I don't think developers who make use of IE/M$ specific 'features' are the same ones who demand standards. They are purely after the dollar return that provides. Also, many companies don't care about standards, they just want to have the customer be able to use their site. This may be one of the few 'back doors' we can use to pressure standards use and even non-IE support.
my $.02...
And I still like
not having to install component parts that I don't want; Composer, E-mail, etc. Just give me a browser, thank you very much!
