Of course, but price doesn't just mean money. I think I read somewhere that AMD was willing to grant Microsoft & Sony more rights over the chips than their competitors. I don't know how much that was a factor though.
-Both wanted x86 for better usability (PS3 Cell was a hard-to-tame beast for many devs, ARM not strong enough)
-Intel was not interested in manufacturing semi-custom chips
-Nvidia simply did not have x86 licenses
-AMD was left as the only option
Of course other things also factored in the big picture, profit margins for example, but those are more known.
That's the result that you want after a long slog of debugging. It's not as fun to dig into something for 12h and finally find a misplaced parenthesis.
I find Matt Dillon's enthusiasm and humbleness admirable. He's been active for donkey's years, pumping out stuff since the days of comp.os.amiga (if memory serves), and created his own filesystem and BSD distro, AFAIK not out of vanity but to do and share research.
People like him should get more public recognition.
