NVIDIA put a lot of effort into making their hardware and accompanying software useful and usable. CUDA by itself might have never got any attention if not for the effort that NVIDIA puts into helping their customers use their technology, effectively. And they are by no means perfect at it. Most of their products are a horrible mess and they often have 7 different ways to do the same thing. A lot of their libraries are closed source and you're forced to use an API that links to a black box. There's lots to complain about.
