AmigaTWO (i.e. the next-gen AmigaONE)
You might have been joking, but there is actually truth behind your statement. Amiga One was supposedly the first PPC NG Amiga from Amiga Inc (based on the Pegasos and "Escena"). It would be single core, hence the "one". It would be followed by a dual core variant at some time, and that would actually be called "Amiga Two". It's teh true!!1!
Really, it is!
EDIT: And this is probably why Hyperion persists with the rather strange version numbering of their OS, i.e.:
OS4.1
OS4.1.1
OS4.1.2 ... etc, etc
What I'm getting at is that IIRC OS4.2 would supposed to have SMP. And maybe they are saving that particular version number for this occasion for "nostalgic" reasons? Not that it will ever have *true* SMP, at least not in a way that it would be recognized as such by "outsiders", at least not without breaking the last parts of "Amiga" it has in it. And I guess it will still be called "AmigaONE"...
