If the Amiga has no future then why do Hyperion continue to develop OS 4.X, or A-eon develop the X1000, or why is the Natami or the Minimig still being developed, not to mention Aros and all the other people working on other projects continue to do so.
You forgot to mention MorphOS. The Amiga had no future when Commodore died. Escom & Co were but shadows of a greater past. But since the Amiga has been dead for about 15 years there is absolutely no reason to give up now. Maybe computing isn“t that much about performance or market-share anymore. While the cool kids move to phones and tablets and have all their data in the cloud, there may be a time of diversity on the PC market again.
