I think that the StrongARM has 14 general pupose 32 bit registers, unless
they removed a few of them since I was programming with the much older
ARM 2. (Maybe the ARM3 as well, but I was never really bothered with
numbers on chips then.)

The StrongARM is supposedly compatible with older ARM code so I guess that
it probably has either 14 or more registers.

Have a look at www.arm.com, there's some more information there I beleive.

Personally, my experience with ARM code (some years ago now) would have me
buying ARM based machines and porting stuff to them. However they
discontinued the Archimedes range (although it was years ahead of the PC
in performance ?!) and there's not been anything else for a while.
Apart from the RiscPC, which was a tad expensive at the time.

Yes, but at least OS/2 was given a chance, it got reviews, it even got
some good reviews, some people use x86 Solaris in the business world,
there's at least a Linux column or a bit of Linux speak in almost every PC
magazine every month. SCO for the x86 probably gets used a bit. People use
Mac's and the same applies for them. There's probably some CAD people who
buy Sun, and some Video folks who wouldn't want anything but an SGI.

However I've not really heard anything about the ARM range for years apart
from it's use in embedded systems. Surprisingly though it's got incredibly
simple asm, it's high performance and it's cheap. Maybe also it was
originally British, which doesn't get you anywhere in the computer
business now does it? =(
