The Amiga hardware is as obsolete as a Sega Megadrive, Super Nintendo, Atari ST etc.
So is the C=64 as well, but that don't stop people from developing software and hardware for it. What is so wrong in doing the same for the amiga.
If some rich "philanthropist" finds out he wants to make some amigha hardware. Would that stop you from buying it, just because its idea is 20 years old... Who knows maybe some amiga guy wins in lotto....
