Well, your posts seem to be talking about how the Amiga doesn't need to have the latest and greatest CPU (ie, 1GHz, dual processor etc), and yes I agree. Whilst it would still be better to have a faster machine than a slower machine, having the fastest desktop CPU isn't the most important factor for the Amiga - for me to return to the Amiga (I currently use WinUAE), it would take a reasonably fast modern machine to be available, but there are plenty of other factors more important than it having the fastest CPUs available.
However when it comes to the idea of how 68k is fine, then I disagree. Of course, I've got nothing against people who are happy using them, but there are plenty of occasions where I value having a faster processor (compilation speed, 3D programming, mp3 encoding, watching videos, playing games), and as a result I feel if there are going to be any new Amigas or Amiga clones, they need to be way ahead of 68k.
Can't the G3? Or does it need more beef?
Well, a G3 might be okay, if the other factors are enough of an improvement over other systems to make me prefer it, and the price is right.
But moving a system with 68k and AGA to a level of performance equal to G3 and graphics cards requires a real G3 and graphics cards. You can't "shatter" this hardware limitation just through clever software tricks.
It's more the other people in this thread that I disagree with; I mostly agree with your original post;)
