Its a nice dream and more than that it is a product that would sell if it could be developed (read: funded). It would require more like $250k to get it to production. The unit price should not be more than $299 and you'd start making a profit after selling 2,500 units.
$250k is seriously not a lot of money - especially if it's coming from and driven by someone that's enthusiastic and believes in the potential of the Amiga platform as a viable niche contender to mainstream OSs.
I guess to some extent Trevor Dickinson fits that bill- I'm sure he took on some financial risk setting up A-Eon and commissioning production of the X1000.
