I agree that the classic Amiga is becoming 'Endangered'. At the end of 1999 I was an expaneded A1200 user, but with the dabacle of Amiga Inc's attempts to restart Amiga range and the complete lack of serious or game software, I decided to jump ship. I got myself a PC. Now I have a wide choice of software and cheap hardware and I can run Amiga s/w via Winuae, I get best of both worlds.
As for AmigaOne and AOS4, its still early days. There is a growing s/w base but its slow and until the final release of OS4.
Rebuilding the Classic Amiga again is a non-starter, the technology has moved on and no-one would buy 10 year old technology again to justify the cost. Lets face it, the classic Amiga will only live on as long as the hardware lasts but every year it'll be harder and harder to find working h/w for it and it'll end up in the annals of history.....
The AmigaOne will take its place as it has upto date hardware and runs our favourite OS. What more can you ask for?
