Here's the facts, folks
If Microsoft did, in fact, have any *VALID* patents that Red Hat was violating, Microsoft would be in court trying to sue Red Hat out of existence. However, MS is well aware that *every single patent they have ever filed* would be overturned in court because of "prior art" or total lack of innovation ("fails the obviousness test"). Ergo, MS *can't afford* to sue Red Hat.
So, fact #1: Steve Ballmer is a lying sack of bovine fecal matter.
Windows Vista has failed miserably in the marketplace. Althouhg MS has succeeded in force many OEMs to push Vista on the unsuspecting new-computer buyer, one of the largest, Dell, will still sell you a machine with Windows XP if you ask for it (because when they tried to force Vista on corporate customers, they bled sales like a whale with an explosive harpoon stuck in). And unlike Halo 3, people who already have computers with older versions of Windows are NOT lining up and clamoring to buy Vista to "upgrade".
Fact #2: Microsoft is in serious trouble. they have enough cash to stay in serious trouble for a long, long time before going titsup, but unless Ballmer can convince people that Vista isn't crap (and he'll have better luck convincing Osama bin Laden that GWB is a devout Muslim), MS is going to lose the desktop; maybe not to Linux, but someone will certainly take over.
And those are all the facts one really needs.
Oh, and since we're talking about Windows - where's the IT angle? After all, Windows isn't an IT product - it's a toy OS for game PCs.
