Made a new partition with Gparted and installed Solaris 11 UNIX Express which has gnome 2.30.2 on it. Compiled a opensolaris Openoffice 3.2.1 on it. One of the new features is it boots up faster and the ZFS file system has encrypting file system.
OpenSolaris 2009.06 was using 111b kernel/Gnome 2.26. Solaris 11 Express is using the 151a kernel. Uses 446 MB with one tab in Firefox open.
Theoretically more stable than Linux
