There are more and more Solaris Live-CD available. I already tested SchilliX a few months ago. Yesterday, a colleague talked about BeleniX, a new one, based on OpenSolaris.
I burned the latest iso image and tested on a HP notebook nx7010. Everything was detected without problems! (FastEthernet, Wifi (802.11g), DVD-burner, touchpad, sound, …). I was really impressed!
It’s definitively clear that Solaris becomes “usable” on day-to-day basis on a notebook…
