Sun has made its Solaris 9 Operating Environment for x86-based architectures available for purchase as a download or a media kit.
The Solaris 9 x86 Operating Environment Media Kit is available from Sun for $95. The kit includes an installation CD, a DVD, a localizations disc, the Solaris Software Companion CD, and a collection of hardbound documentation. It also includes the GNOME desktop environment and StarOffice 6.0. Unlike the Sparc edition, it does not include the evaluation copy of Oracle 9i.
The software is also available for download for $20, direct from Sun's site.
