After Oracle took over SUN and they dropped OpenSolaris I stopped using or even looking at it. Now a customer is keen on going the Solaris way and I have a chance to get my hands on it (again). I dont have a SUN SPARC sitting here but Oracle continues to support i386 architecture and they have both the iso file with the text installer and even a ready to run virtual appliance ready to download (link). Oracle released version 11 of Solaris on 2011 November 9. Did you know SUN’s first OS goes back to 1982 as Sun UNIX 0.7 ?
I am not sure what happen to Solaris Express 11 which disappeared completely from Oracle’s website. Will there be another Express version for “free”/development/evaluation use ?
