I'll concede ill-positioned, but the 128 was the logical upgrade for 64 owners, not the Amiga. CP/M was always a tack-on to deal with the incompatibility of the CP/M 2.2 cartridge, which is why the Z80 was on the logic board in the first place (Bil Herd has explained this in detail). Your post basically says the 128 sucks because its CP/M implementation does (which I won't dispute), but the 128's native mode is a lot stronger than CP/M and you got nearly perfect 64 compatibility to boot. That wasn't "bad" as a follow-on to a stratospherically popular home computer.
