I think the main problem here is that the computer market has changed from the 80s... and not just the proccessing power available. When the Amiga first appeared it was a huge jump in capability over the 8-bit machines we were using back then. These days, any improvements are just marginal over an already advanced state of the art.
That's exactly why I consider desktop computing the last place the Amiga souls should try to reincarnate. One thing is AROS, which I consider the only viable 'future' for the old Amiga habits in the PC era, the other is what I imagine about an Amiga platform rebirth: it might be a tablet-like device with unique features smarter people than me should transform from dreams to reality. Something I can wear, for instance, which will augment reality. Think about a pair of special glasses that may integrate a GUI-overlay to the real environment and work with the movement of eyes, but definitely not a old, big, heavy, ugly desktop minitower.
