Do you want to believe the MacIntel transition was painful in order to validate some other idea, maybe something to do with Amiga?
Mac transition from PowerPC to Intel was amazingly easy. I assumed they will suffer for it but thanks to complete lack of regard for customer from Jobs (it's a good thing, you want keep your PPC Mac? Fine, consider yourself EOLed) and Rosetta PPC to x86 JIT did smooth the transition. I don't know any Mac user today that would long for PPC Macs.
Remember PPC as cooprocesor, kernel wars? That's how Amiga switched from M68k.
