@MiAmigo:
I note that your emphasis has shifted from technical matters to matters of 'elegance'. Which is fine, but does not quite address the issue at hand. You claim PocketPCs and notebooks even get quite a lot of bang for the buck, and even run cooler too. True, very true. But nobody is expecting them to run Doom III or Half Life 2 at 1600x1200x32 at 8xFSAA and over 80 Hz refresh rate either. Whether you need or want such insane specs is quite another question. (I would not, my monitor cannot cope, so why bother?)
In addition there is always the tendency of people to buy 'for the future': buy a too-fast card today so it can be normal specs tomorrow, and while not perfect, be adequate the day after. It takes a strong will to buy a lower-spec model just because you know you won't need anything faster and if you can just as easily buy the faster model! 'Elegant' and tight solutions are much harder to upgrade: I have yet to see people upgrade their PocketPC and notebook. Instead they sell off the old one, and buy a newer model. The Amiga, 'elegant' as it was, proved to be a {bleep} to upgrade, as many A500 owners found out to their detriment as magazines began to show all the benefits of faster machines. (CPU upgrade usually caused problems with the caches or conflicted with stock standard hardware on the expansion port, Kickstart upgrade messed up games and demos, and if you wanted different graphics or sound, well, you would be very much stuck.)
With that all in mind, and going back to 'hot' and 'noisy' nVidias, I am not at all sure whether you could do much better than is the case now, given, of course, our current state of technology, and the fact that it is a consumer product, so cannot be overly expensive. That is elegant, in a way, but of course not the 'elegant' you had in mind.
