Porting code from one to another often is no more than swapping in the right interrupt vector table with everything else being the same.

One of the nicest features of the AVR line. 
Take a 2343, with one timer, one external int, some ram, EE, and registers.  I can take code from that chip, and drop it into a Mega-128 with only very minor tweaks. :)

It's nice not having to relearn every peripheral, when you change chips within a family.
