Seems much cleaner. They should do a comparison of how much screen space is used by the chrome vs. other browsers. Can't wait for this to high the nightly / dev builds.
I've been running the nightly, and there was a brief period where the tabs were moved into the title bar. Not sure why they backed it out, but I didn't really like it anyway. (I kind of like knowing the title of the page I'm on -- for instance, with this particular link it conveyed semantic information that was missing from the page itself.)
