I kind of get the feeling from this post and some other that if we cant create a machine as good as the A1000 was in 1985 in todays world we shouldn't even both trying.
I'm sorry but thats a very tall order, I mean most of us know just how far ahead of the competition Amiga was in hardware and software, as you pointed it out this is what the big console companies try to do and spend millions into trying to get something that way ahead of the competition but as ps3 and xbox 360 proves they dont really leap frog the computer industry to build something like that you would need to pretty much build what todays super computer are for the home, maybe if an Amiga user knew how to build a quantum computer we have a chance, anyone holding something back?.
I think hardware wise its just to difficult to be way ahead, offering something different that the competition cant do is I think a better solution, a bit like what Nintendo did with its wii remote, can that be done in hardware for computers, well we got Xmos, that will hopefully show us something that the competition couldn't easily do, and is there anything that PPC are much better at than x86? But software wise it easier to try and offer something different.
I think A-eon are doing what they can, they called the X1000 the most ambitious project, well is it ambitious enough, well I think it is the best we can hope for with money/investment and community support thats left. It might of been too ambitious because a project like this might even be to costly for the Amiga community to support, and thats a real shame.
