In this case NVIDIA provides me with a driver that works. I'm happy. I don't care what Linus has to say. NVidia, in my book, is supporting Linux on the desktop and for that I am happy.
NVIDIA has been providing stable, fast, feature complete drivers for years and have supported Linux and FreeBSD just as well as they support Windows.
ATI, on the other hand, released specs years ago and the open source drivers are still unstable, slow, and incredibly buggy. The Intel drivers seem a little more stable than ATI, but they're still ridiculously slow and not feature complete.
I develop 3d software on Linux (and OSX, Windows) for a living and I test NVIDIA, ATI, and Intel gfx hardware on a regular basis. The NVIDIA closed source driver is the only linux 3d driver that is acceptable for doing real work. Period. It'd be great if the open alternatives were decent, but they're not.
