I don't have any specific axe to grind with regards to Intel other than, in my humble opinion, their x86 architecture is appalingly bad. The IA64 (Itanium) I know little about (I think its VLIW), problem is I am not sure what Intel wants to do with it (at one stage I think they dearly would have loved it to surplant the x86 - but (alas) it's lower clock rate (not performance mind you) doomed it to small niche markets). AMD's ascendant x64/Athlon 64/opteron family probably put the last nail in Itanium's coffin (as Intel had to fight back with an x86 chip to compete against AMD's offering)s. I digress.

The point is *not* that you can't abstract an OS to run on any processor - but that given RISC OS's *lack* (relatively) of abstraction that you'd lose a lot in the translation. As over 40% of RISC OS is ARM Assembly language - so an inability to run this code optimally (i.e., Natively) would have a detrimental impact. Bear in mind some of the remaining 60% of RISC OS is written in BBC BASIC - and that would probably be best executed by the native ARM BBC BASIC interpreter (so again a "non-native" processor would be at a disadvantage). You are, of course, correct that for C/C++ (a sizeable amount of RISC OS) would not be so hampered and would be more processor agnostic).

I don't personally believe that ARM will simply withdraw from its niche and allow Intel to roll in with 1-5Watt x86 cores that would be competitive. ARM, IMHO *have* to up their cores performance - or lose market share. That being the case I would like RISC OS to be in a position to take *advantage* of those changes.

As to Linux users being open minded I did not infer they weren't - all I was saying was that their primary interest *IS* Linux - I can't imagine that that would change if they were offered RISC OS. As to the cost of RISC OS that's set by ROL - and the price they charge they charge. If the "hardware production cost" you refer to are Flash RAM (or even CD) they represent a *small* proportion of the price - and consequently I'd not foresee a big drop in price - and without that drop and a viable fast Linux based emulator I can't see enough Linux users opting for RISC OS to such an extent that economies of scale would result in a larger drop in price that might encourage further RISC OS use.
