Windows gaming is a key part of M$' success. The one thing that sets M$' platforms apart from its competitors are their viability as consumer products.
Gaming plays a very, very small part of that. Look to total gaming revenue for all of PCs compared to Windows revenue alone.
If (when) M$' dominance in the consumer space falters you will see alternative OS'es (mainly Linux) really take off in the business segment of the market completely undermining its sources of revenue.
Linux needs Office to take off. Office is the overwhelming driving force behind MS's dominance in the business world. At the company I work for we have a rather diverse mix of different platforms in use, including Linux and OS/2. The actual PCs all run Windows and nearly all of them have one thing installed on them besides to OS, the Office suite. The company my mother works for has the same situation(although they run Unix and don't use OS/2). Office is the reason they have PCs. Linux may do fine in the enthusiast or server market, until Office is ported it doesn't really stand a chance in the business segment at large.
M$ knows this and it knows that Sony is looking to offer more compelling products to the average consumer, that is why it entered the console race with the Xbox which is really nothing but a scaled down PC disguised as a gaming machine - a trojan horse.
It's a trojan horse for the digital hub which is complimentary to PCs, not replacements. It has the potential to be an enormously lucrative market, but anyone who thinks it will replace the PC isn't thinking straight.

PC game sales suffer heavily from warez.
How many people do you know that have never used a warez Windows copy?
And it's indeed a major reason why Windows is on top. I know a ton of people who only keep Windows around to play games.
The amount of people who use Linux total, dual boot or not, is ~5% of the PC market(according to market research cited by Linux advocates). Be is dead, Irix is a far smaller niche, Macs are accounting for ~3% of the market, there simply is not, nor has there ever been, a mass of people waiting to drop Windows as soon as games get ported. If it were the case, titles that are ported to Linux would actually sell, which they don't. Loki Games went under for a reason, and it wasn't because Linux titles were tearing up the charts(or even making a very weak appearance for that matter).

In other words you pulled that 15% number based on nothing tangable.
I would have to agree, 15% is
far too generous. Look at the amount of titles releases for the PC each year and how many titles they sell on average compared to consoles, then factor in the installed base of PCs is greater then an order of magnitude higher then the consoles on a global basis. PC gaming is plenty healthy enough to staty a viable market, but it is very far removed from being close to a driving force for the mass market.
Look at the best selling graphics solutions, integrated Intel. nVidia's best moving product for several years was then TNT2 M64 and TNT Vanta. Add in graphics boards are the exception in the PC world, I'm actually relieved when someone wants me to upgrade their rig and I see a POS M64 in there, at least they have an AGP port which isn't that common in today's market. Decidedly low end sound solutions are also the norm.
If you want to say that gamers are pushing the envelope in terms of driving CPU and GPU technology you can make a very strong argument, but top tier products(fastest current CPU or GPU) tend to account for far less then 1% of total sales.
