I have been using it since it was in Beta, and am updating as they continue Beta in the updates before they release them to the public as updates.
Im actually loving it! I never really liked the toolbars of any sort, and turn them all off anyways. If you know your not browsing in virus laden areas, then why would we need a toolbar to tell us it is safe. When I was using any of the toolbars I never noticed anything different the toolbar did that I wasnt already doing, and the toolbars were just cluttering up my screen as far as I was concerned.
So, so far it has been great! Less clutter at the top of the screen, and a bit faster at the searches.
