It does matter what he *thinks*.  His perception of Linux gets spread to all 
he comes in contact with.  You have NVidia on one side welding their the hood 
shut from the inside, then you have Red Hat on the outside welding the hood 
shut.

So he should walk away from Linux because he wants good video performance?  
There is no 3D hardware available with open source drivers that is on par 
with the closed source drivers from NVidia and ATI.

Lets go one step further, the NVidia drivers are even encrypted!  Thats right, 
encrypted, they get unencrypted at run-time.  NVidia and ATI do not want to 
expose their trade secrets to the competition so they close source their 
drivers.  The driver support is horrible from both companies.  I do not 
believe that we are going to see an Open Source GPU on the level of NVidia's 
anytime soon.

Its going to take HP or IBM to get behind a product to get NVidia to jump.  
Red Hat simply doesn't care because the driver is closed source.  Even if Red 
Hat did care, they do not have the in-house expertise to resolve video 
issue's.  They would just simply pass it on to NVidia, so they tell us to go 
bug NVidia, because thats all they would do if they did support NVidia.  
Sometimes the video problems are a complex software/hardware issue and 
looking at what changed in the kernel might get the driver to compile, but it 
doesn't mean that your video card will work in video mode X with zilion 
colors, AGP 8X, and SSB on.   HP and IBM have the in-house software/hardware 
developers that can drive issue's to the bit banging transistor level.

Can you blame NVidia or ATI either for their stance?  I cannot.  What is the 
ROI on a Linux driver?  Probably not very good.  The mere volume of the 
Windows install base will drive NVidia business decisions unless you have 
someone like HP or IBM behind a product line.  The same goes for Red Hat, 
their ROI on a closed source driver would be horrid also.  How many Red Hat 
Enterprise customers need a NVidia 5900 FX Ultra for Quake III games?
