Just down loaded it and installed took about 20 mins in total including reboot. as far as i was concerned so far no problems. after install it will ask some questions and you are ready to. more reports as time goes on
Fairly slow at loading pages at times,tabbed browsing isnt as quick and as smooth as IE7 not keen on the yellow highlight it adds to tabs either,images take longer to load and have a distinct blue tinge until fully loaded that might just be my settings but it didnt do it with IE7,but it does look smoother apart from that,i have only had it a few hours and have not tested all my add-ons like Flash/shockwave/jave yet so untill i do i cant say if its better or worse for those.
