Here's what I wrote at the very end of the very last Enterprise Unix Roundup of 2006:
"In all, 2006 was a pretty steady year for Unix. It's still losing deployment ground to Linux and Windows, but the Unix vendors aren't even close to giving up. As long as Unix is tied to non-commodity boxes, there will always be a reason for vendors to try to keep Unix alive."
Apparently, there's a good reason I am not in charge of a multi-million-dollar company. This whole notion of sticking with non-commodity boxes? Boy, what a crackpot idea that turned out to be, particularly if you're Sun Microsystems.
Of all of the enterprise Unix vendors, it's pretty much a slam-dunk to say Sun made the most dramatic moves in the Unix space in 2007. IBM and HP held their own, seemingly in a holding pattern of quiet deployments that kept them in the top revenue and units sold positions for the year. But, still trying to find a beachhead into the higher sales numbers, Sun put Solaris and its umbrella OpenSolaris Project through some serious paces.
