I know we have a few Solaris users here, just wanted to point out that Opera will no longer be available (..at least, newer versions).
In order to ensure a consistently high quality browser across our most popular desktop platforms we have reluctantly decided to drop support for Solaris. This will allow our UNIX development team to focus all of their attention on bringing Opera for Linux and FreeBSD up to final release quality, meaning that a 10.5x release for these platforms will happen as soon as feasibly possible.
Please be assured that we have no plans to drop support for either Linux or FreeBSD. These are the preferred UNIX-like environments of our development team and hence fully supporting a browser on these Operating Systems is more straightforward.
As always, the Desktop team will continue to consider adding support for further environments and/or processor architectures in the future.
