A number of points:

(1). x86 Have *far fewer* registers than the ARM, yet no complaints (curious).

(2). The ARM instruction set as far as it goes is fine (ok, there'd be one or two instructions I'd like added but I'd live without them). You could bloat out the ISA to the point where the chip would take longer to figure out "which" instruction was being asked for than the time taken to actually execute it and you'd wind up with a CISC chip like in the 1980's but where would be the point in that.

(3). RISC OS runs best on ARM, no emulated system yet equals the performance of ROS on an actual ARM and I don't think one will be likely in the next 3 to 5 years (by which time the ARM will have moved on and the gap will have been restored).

I'd agree with Dougal that ARM are not exactly all sweetness and light when it comes to potential patent infringments (I can think of BlackARM and PicoTurbo as examples...). They (like Intel) do tend to get a bit "heavy" if they perceive their Intellectual Property as being threatened.

The big difference is Intel controls possibly 90%+ of the processor market, ARM doesn't. Any excesses or pressure Intel applies is far more telling (and more damaging) to competition.

That having being said I am actually sorry ARM doesn't have competition as Intel does as it would force them to upgrade their processor performance in a way AMD forced Intel to do in the x86 field - and we'd all benefit.
