Just exactly what "high end of the market" are we speaking of?  The high end
of the market either uses someone else's RISC processor (usu. NOT Intel's  --
MIPS tends to get a larger share of _that_ high end market) or makes their
own (i.e. supercomputers and the like).  If you're talking about high end PC's,
you're _still_ mistaken.  At least from _my_ experience, most programmers
prefer Motorola assembly over Intel.


I also have a few questions about your statements:

1)  Just what advantages are there in "Isolated I/O"?  (IMNSHO, "Isolated I/O"
    is a PR term describing the song and dance one has to go through to do
    I/O on an Intel machine.)

2)  Just what disadvantages are there in memory-mapping?

3)  Why isn't there a popular Intel machine with an OS better that MessyDOS?
    (OS/2 ("Half OS") and Windows don't qualify as better -- just different.)

4)  Do you really believe that the reason that the market has clung onto the 
    IBM "standard" is the Intel processor in it?  (Analogy:  We've known
    that cigarettes were bad for us twice as long as we've known that Intel 
    was  --  it's just habit.)

And lastly:

5)  How can you defend a company that constantly breaks away from the standard
    and starts their own?  (Remember EPROMs?  Couldn't make them ROM pin 
    compatible.  Noooo...)

...of course, _some_ Intel chips are nice.  Just NOT the 80x86 or the i860.
