Rated 1 out of 5 stars
Way too buggy for release. Had to restart browser to visit a url a few times among other things.
Reviews - as a web developer who views the url of the site I'm on constantly, greying out the secondary part of the url (everything but the domain name) makes it much harder to read. I disliked this feature with Chrome as well.
My personal opinion is the awesomebar didn't add any significant functionality and actually made usability worse (even without the bugs).
