And how did you draw such a conclusion that they are both Macs. The Mac was originally a 680x0 and although overburdened (unlike amiga) had some support hardware like for audio/keyboard/mouse etc. so unless you have a system that is a subset of that hardware configuration you can bet there exists a program that will work on original Mac not on your so-called Mac.
I didn't own any of the m68k Macs, but I've used them. Considering some evolution, these PPC and x86 Macs look and feel the same. They run much of the same software (although now much more advanced). Frankly, I don't give a poop whether the underlying HW is m68k, PPC or x86. All of them work. x86 works faster than PPC. PPC works faster than m68k.
This is how I feel. I consider them Macs. Obviously you don't need to agree.
