Maybe you are simply seeing what you want to see?
Also, not everything everyone has or has had is going to be in their sig, and even when it is, this does not automatically imply bias. I bought most of my current ATI/AMD cards when I actually preferred NVIDIA, because NVIDIA hardware was unsuited to the OpenCL work I was doing at the time. I still prefer my GTX 480 to my 6950 for most things.

You have a quote that lists potential, but you aren't mentioning actual implementations.
No one is talking about what hardware PhysX could hypothetically be used for, as this is much different from what, in the overwhelming majority of cases, it actually is used for.

Hell, out of the stuff you listed only 2 change gameplay (Characters and new weapons) and I've never seen either used to any extent, that's why PhysX will fail...It'll never get fully used because to do that is to limit yourself to nVidia and nVidia alone, unless you want to hope nVidia plans to make the CPU PhysX better. (Which, to their credit, is far better than it was)
Havok is used in HL2 and Crysis uses its own engine, both games enable you to use physics objects to your advantage and would be substantially different games without...UT3's liquids would look different and there wouldn't be a small map pack. Yawn.
Havok and PhysX are both proprietary physics middleware. Neither Havok nor PhysX need special hardware to be used and both can be used for "real" physics that actually affects gameplay.
There are actually games that use PhysX for all in game physics, and that cannot operate without PhysX, again without necessarily needing NVIDIA hardware. BulletStorm is a good example on PC. Hell there are even one or two Xbox 360 games that use PhysX, like Castlevania: Lords of Shadow
Hardware PhysX is where we run into issues. If effects are dramatic enough to require
hardware PhysX and
are also integral gameplay affecting components you won't be able to sell that game to anyone without a decent NVIDIA GPU, because it either won't work, or would play very differently.
