"OpenSolaris is Sun's open source version of the Solaris flavour of Unix, and is primarily aimed at workstations. As a relative newcomer to the open source world, however, the platform has lacked a broad selection of applications, while hardware support has been narrower than for competing Linux distributions.
"The new release, version 2008.11, was intended to address such issues, while emphasising Solaris-only features such as the ZFS file system. New hardware features include support for suspend/resume, 3D graphics acceleration, support for SD cards and better audio-hardware support, Sun said. Suspend/resume currently works on a limited range of hardware platforms from Toshiba, Lenovo and Dell, as well as Sun's own Ultra workstations."
