It seems to me that this sentence points us at a key question in this King versus Gorilla debate, i.e., what does and does not constitute an Open Proprietary Architecture in this case. One might, for example, claim that the AMD license was the very thing which makes it open rather than being the thing which makes it no longer proprietary. Or, one can take the view that the CPU is one chip in a larger system, much of which is dictated by the interface to that chip, so that it is the system which is open and the chip which is proprietary (except for the AMD issue). I also think it is important to realize that the AMD license only dealt with the architecture of the 386 and while the whole x86 and Pentium family (so far) has retained a common instruction set, what one *does* with that instruction set has changed enormously since the 386. Intel's changes in this regard are proprietary to Intel and AMD has had to figure out its own ways of attaining comparable (or better!) performance without violating Intel's patents on these extensions.Itanium has the potential, as a new architecture and with a new value chain, to induce a huge tornado. Remember, that Intel has recently stated that the world only has something like 1-2% of the servers it will need in the next few years; again, this need is Internet-driven. Yes, but it also has the potential to not be the product that wins the tornado. To be sure, lots of manufacturers have hedged their bets by working on IA-64 products in parallel with their RISC or x86 products, but this doesn't become the heart of a tornado until the customers start picking the IA-64 boxes over the other alternatives. This is a very different situation than the one by which Intel came to dominance of the desktop since there are lots of other very mature offerings already in this market.
