i agree on all of your points, except the very last one, but only slightly, amd did have enough clout to get microsoft to make a new 64bit version of windows, before Intel even announced they were ever gonna support x86-64. and didnt amd start the ddr phase. i think amd was the first to use ddr with their thunderbird chips, but i could be wrong on that.
Yeah, it was really more of a generalization. AMD has pushed AMD64 and HyperTransport out mostly by themselves, which means to me that they know which feature are critical to their platform and which battles fo fight. But if you compare this to the raw number of technologies that Intel either designed, had a major hand in designing, or pushed ahead, AMD comes up looking a little timid.
And no, AMD didn't have a hand in the design or spec'ing of DDR (AFAIK). They were the first to sell it on the desktop with the AMD760, but that was because Intel was tied to RDRAM until 2002, but the standard was being pushed foreward by pretty much everyone else, namely IBM, Sun, etc .
