Wine will run IE if you absolutely need it.

I tried the IE 8 beta. It is horribly, horribly slow. It makes IE 7 look fast. And the standards compliance is a joke. I tried the ACID2 test and got like a 37. IE 8 did feature many Flock-like features. You can select text and right click on it to post to a blog or whatever. However, it defaults to using Microsoft sites and services for everything (which isn't surprising).

Most of the time you can spoof the user agent, and make a page load that demands IE. However, if you need ActiveX, then you really need IE.
