Yes, I agree.

Everything is relative.
A PC cost you 500 dollars. and a PC cost you 12000 dollars. The requirement is different, the need is different.
I will use ATI for cheaper build, but use Nvidia for high end build. When we buy a 12000 dollars new toy, I really don't want to save the 2000 dollars and later I found that it is not compatible with my hardware and my cool new application.

ATI currently has the lead by a large margin in terms of performance at least until about March/April 2010 and it is believed that NVidia's Fermi may not live up to expectations. ATI has more energy efficient silicon (more FLOPS from a smaller die) and their cards are cheaper.
> Nvidi has more than one product. Cool. Sun and Dell sell both cheap hardware, tell me why IBM and HP rank top 10 of fortune 500 and Dell and Sun are around 100? Hardware price is a minor bit of your TCO maybe.

ATI has also just released  OpenCL as part of their Stream SDK which makes OpenCL (standards based GPGPU) available from both vendors. Benchmarks are putting ATI in the lead.
> Just released means that less mature? Can ATI support all device now? Because according to history of Nvidia, they can. I do believe ATI will catch up soon too. But maybe not now. So what's to advice other people then?

Fermi sounds quite cool but it is late, may be under-delivered, and is definately going to be a hot power hog.
> Hot? This is why it has a fan or two in the design.

BTW I have two NVidia GTX285's so I am unbiased :)
> I own about 200 each for now. So make me more unbiased? What's the logic again?

Happy new year.

This might change some of your minds about NVidia:
