Just installed it! It seems to be lightning fast, but that may be an illusion. I have not looked into add ons yet, that may slow it down. It will have to be good to keep me away from Firefox.
Edit - Getting this at the bottom of all the forum pages-
This web page is not available.
The web page at null might be temporarily down or it may have moved permanently to a new web address.
It is still a Beta so it might just be a midgie(small bug)
