Just tried it, a couple of things people should know before installing it
1) It still doesn't render a lot of CSS properly (fails the acid 2 test spectacularly) and actually seems to have some rendering bugs that IE6 doesn't
2) Theres not enough control over the toolbars and it's impossible to get it into to a useable state like IE6
3) The bookmarks link fills the page instead of scrolling, my bookmarks exceed the width/height of the page and I can't see how to get to the ones that aren't shown, possibly alterable in the options, can't see it though
4) After rebooting post install, it causes Trillian to crash constantly.
5) Doesn't appear to be uninstallable, it upgrades IE6, make sure you set a restore point before installing it so you can then
UNINSTALL IT COS IT'S RUBBISH!
Unfortunately I forgot to set a restore point and now I'm stuck using Opera
