Amithony,
Bang per buck is clearly going to be better.
No, it's not. The real Amiga was able to do things that no other home computer could touch, it *had* bang for the buck. OS4 doesn't do anything you can't do on any other commonly available commodity system these days, OS4 just does it a bit more clumsily.
Think back to the 80s or early 90s what the Amiga was like. Didn't you ever try to imagine what Amiga would be like in 20+ years? Now, think about OS4. Does it match your expectations?
