You can't make a post like that and not provide facts of your own. To make a point you need to find up to date, reliable sales figures from ATI and Nvidia.
And if I were to make a guess (which is all we can do till you find your statistics) then I doubt NV sells 3 times as much hardware as ATI. Yes, maybe in the enthusiast market but ATI has a strong presence in the mainstream and budget areas.
Low end graphics by nature are pretty "discrete", not literally

People with the higher end cards play games generally (I would guess that there are at least 3 x more nvidia owning gamers at the moment than ATI)
Games and intensive stuff crashes computers, coupled with overclocking and what not...
I'm just saying that the way you put your post seemed to be sensationalising like the news of the world might and not actually reporting the facts of the matter, but cherry picking the results not taking everything into account.
There was certainly no need to start a thread with that small amount of info you provided
