That really is weird.  The instruction set on a PIC dates back to 
1975.  The AVR is about as primitive.  The MSP430 is more PDP-11-ish. 
 One minor gripe that I have is that the uC community seems to put up 
with really lame assembly-language tools, insisting on using C 
instead.  Many are Harvard architecture( not the MSP430), which calls 
for some re-thinking, but otherwise they're no different at the core 
from any other microprocessor.

Maybe that's where my attitude is similar to Tony's--I still love to 
write a nice clean piece of assembly code.  Yes, I can do it in C, 
but there's something more satisfying working closer to the 
architecture.
