Re: nvidia reactions to Greg Kroah-Hartman's announcement.
Well, that's one reason that Nvidia is the number three video card manufacturer.
Their Linux support is second best (after Intel). Their GPU performance is better, but now that both Intel and AMD/ATI will be competing on performance, I don't expect that lead to last more than 3 years.
By then, Nvidia may be picked up by a third tier CPU vendor (maybe VIA) in order to compete with the CPU/GPUs from Intel and AMD. I've been in this industry for over 30 years; I can wait a few more.
