you can get version 9.0 through softpedia. I don't know why its not offered via opera.com.
One thing I don't like about opera is that it likes to 'phone home' everytime its opened. It may just try to find any new updates, or maybe share some other info with home. Peerguardian is able to block it, but since peerguardian even lists those IP addresses they could be spyware related, since there is no ad-aware with opera.
