ive been using beta 3 ever since it came out, and there are things it in that firefox does better and things that IE does better. One thing i really like about IE is its very fast, actually quite a bit faster then Firefox, and i really like the new layout i think its very good and there is finally extentions. But i still dont fully trust it because activex is still there. and there are no themes, other then that its a very good browser.
