Oh, I definitely am! It's always cool when someone with domain specific knowledge drops by and proceeds to shatter that dream with technical reasons that are cool nonetheless, the same way how LPCAMM2 doesn't work with every platform either and how VRAM has pretty stringent requirements.

That said, it's understandable that companies are sticking with whatever works for now, but occasionally you get an immensely cool project that attempts to do something differently, like Intel's Larrabee did, for example.
