PPC (or x86) really is the only way ahead now - while AmigaOS might be great on a 68060, it simply doesn't have the number crunching capabilities needed for modern applications (particularly games). I hope that a lot of software that could run on the 68k Amigas is still ported to them though.
Now I read the threads that after all the development on AOS 4, the best I can get is a PPC "feeling" like a fast '060. Well I have that, so what's the exercise for?
I think you're referring to the GUI responsiveness. The reason that it wasn't far quicker than a 68060 at the OS4 on tour and Amiwest presentations is that intuition was running through an emulator (not even a JIT emulator) - I believe that intuition is now PPC native, so this problem will have gone :-D
