P.S.. Another interesting thing to consider is that original Intel patents on i386 are going to expire sooner or later. Give it some time and we might see completely open source i386 IPs one day, free for anyone to grab and use. By today's standards i386 is rather trivial platform with many indepen

That again is very subjective view, David. Sorry. Arm32 is kinda kind of the hill these days in the low-power/low cost space, but arm as a company is much more interested it seems in going into server / mobile device space rather than solidifying it's current de-facto kingdom.
