Very nicely put.

Of course one reason for that is the success of the 8080, and its 
successors the 8085 and Zilog's Z80 (which had an even less regular 
instruction set).

AIUI Intel had a world leader on their hands, and felt that having some 
sort of compatibility in the next generation was important.

While the 6800 had some success (and the 6809 was my favourite 8-bit 
CPU) it was nowhere near that of the 8080.
