So what are we to make of the latest niceties between Sun and Microsoft? The news this week is that Sun is an official Windows Server OEM, which means just about every enterprise application Redmond makes will soon be available for Sun's x64 hardware.
Even more intriguing is the side deal that has the two companies collaborating on compatible versions of Solaris and Windows. That would open up the possibility of both operating systems behaving nicely when they are virtual guests in each other's houses.
There's no doubt, the list of applications Microsoft brings to the table is impressive -- MS Virtual Server, SQL Server, Exchange, even the IPTV server -- and Sun users are probably still savoring the buzz of third-party software after having been in a closed shop for so long.
But like Mac users are finding out, separate hardware and software vendors have someone else to blame when things go wrong. The two companies say they will work closely together on interoperability and other issues going forward, but we'll have to see if that means helping actual customers when their systems are down. And we know that bygones should be bygones, but these two companies haven't always gotten along too well in the past.
For what it's worth, my best advice would be to experiment with it for now if you feel you must, but don't do anything too important on it just yet.
