I can't find the link anymore, but there is the hacker song 'Bye Bye SunOS 4.3'. Its quite funny. If somebody has the link.

It really is an incredibly important part of Unix history, not just Sun. It basically really started the outright Unix wars. Had Sun just gone with BSD and tried to create that as a standard, they could have taken most of the world with them without creating a massive blowback counter-reaction that their alliance with AT&T provoked.

And AT&T would have been dead in the water, they might have tried with somebody else, but that would have just cast Sun as the good guys and AT&T and whoever as the bad guys and with Sun already being the market leader, that standard would have been pretty dominant I would think.
