How so? What niche do you think the 8051 fills? I doubt if the good folks at
Arm would like your comparison. Is the Arm as a standalone processor going to
be made by everyone and his brother like the 8051? Are Arm tools going to be
freely available all over the net? If so then your statement might have some
merit.

They actively foster the comparison.

It depends what you're asking. ARM makes nothing tangible, in case you
didn't know this. They are an IP company. So the answer to the question
"are ARM cores going to be fabbed by everyone and his brother like the
8051?" is "they already are". And ARM likes this just fine, since they
get a bite of every single one. That's their business model.

They already are.

The 51 is not a niche. It is broad market. AVR, XA, Rabbit etc are
Niche.

They actively promote it. The 51 is like the Jeep.  Old, has it's faults
but is everywhere. "Everyone" has used one.  "Everyone" knows it.

They want ARM to be seen as the generic processor you go to when the 51
is not powerful enough for your project.  Default choice 51 or ARM
(unless you need something special)

No. I doubt ARM core will ever be availible like the 8031/2 8051/2 was.
ARM do IP cores.  Everyone else will use the core to produce stand alone
part with ARM core and peripherals.

Why free? That is largely irrelevant for professional development.
Though Lewin and I disagree fundamentally on this point :-)

However the answer is yes.  Lewin's book is about GNU & Linux for ARM
(Atmel ARM7 parts).  Most commercial ARM debuggers come with a free GNU
ARM compiler. 

Though for the professionals :-) there is a very wide choice of
commercial compilers and tools.

ARM don't make processors, just just design the cores. Tons of compaines 
make CPUs based on the ARM code.

They already are. The GNU tools are fairly decent.

Hi,

I can assure you they do like it a lot!  ARM related companies offer
many devices for different target markets and yet, there are still
SOOOO many more 51-designs which ARM would love to get hold of, once
all these designs migrate.
