Many of these ideas are "neat!"
But let's look at the numbers: The latest & greatest (by some opinion) Amiga is the X1000; price? About 2 grand USD. Number sold? I don't know, but I guess maybe a few hundred. Number of active Amiga users worldwide? Maybe 5,000. The number who just want to play retro games? Let's guess 1/2 to 2/3rds. The number of new, non-Amiga users, "Techies," who would buy a new Amiga? Probably the same number who bought an X1000 (mind you these are folks who may have heard of the Amiga name, could afford it, and decided they could put to use such a machine)? Maybe a few hundred.
So, how do recoup your R&D? You all answer that question, because 600 USD doesonly go very far.
[The main question, by the way has a punch-line if you add an "s" to the word "bang"]
