As many posts showed, Solaris is NOT the most "advanced" OS. All pro-Solaris posts insist on reliability (granted), and superior support (valid only in a very few countries). "Advanced" has a meaning of bleeding-edge which Solaris definitively is not. In fact I suspect that the recent commitment of Sun to OpenSource is recognition of the superiority of the OpenSource Model in matters of fast, research grade, development of an OS. In house refinement for reliability by Sun could then give them the best of both worlds. Michel. -- Michel Loos <loos@qt1.iq.usp.br>
