You're mixing up the concepts. What kolla means is that Morphos is restricted to one piece of hardware by license. The Amiga systems you're referring to is restricted by physical compatibility issues, if at all.

I agree with kolla that the license model is awful. Not only because the locking thing, but also by the fact that the license forbids you to use Morphos with an emulator. Modern operating systems are supposed to be virtualized for damn sake.

Anyway, as I see it, Morphos is nothing more than a toy which can be fun to use occasionally. Therefore I've registered it for my Powerbook, despite the ugly terms.
