The adblocker in it has been greatly improved. It does about the same things adblock does in firefox and while the filters may not be as far through as adblock plus, I'm not seeing ads on any sites I go to.
The spell checker works as good as firefox. The mouse gestures(which has become a requirement of mine now) work just as good as anything opera or firefox has.
It ads inline search(like firefox, ctrl+F) and allows you to highlight all words searched for like firefox. Great and now essential feature for me.
The easy homepage or "speed dial" a la opera is awesome. It even one ups opera by allowing me to get the picks from my bookmarks(what the heck were they thinking at opera not to do this?). And because it has a google search box in it, I'm actually compelled to possibly use it.(still using google for now though. Hard to change sometimes).
"Clear Private Data" like feature from firefox. Another thing I really like.
It has lots of other features too but those are the ones I use. I've been used to the IE interface for some time now(actually I prefer it, especially for the way bookmarks come out of the toolbar and disappear once I select one. Also it minimizes screen use by not having as many toolbars as other browsers.)
Definitely worth the try if you haven't used it before or worth trying again if you had problems in the past with it.
I cant say I'm going to use IE forever now but right now it seems ok.
