Amiga burst onto the seen with advanced technology and died an early death. It's the Elvis of personal computers! There never was a survival strategy, and even if there was it wouldn't have worked. The only non-MS compatible computer company to survive that era is Apple, and they survived because of Steve Jobs and a small investment for MS.
I'll repeat that THERE WAS NO WINNING STRATEGY. There is no winning strategy today to bring Amiga back. There is no way Amiga could catch up with Apple or MS, and catching up isn't good enough to generate customer, you have to really excel. Where is Amiga going to do that?
It would take ten's of thousands of man-hours to modernise AmigaDos and then more to develop a killer App. The hours aren't there, the skills aren't there. Look at OS4, we've all got copies of it from various sources, not one of us can make it run on old Macs, or Pear PC. This is child's play compared to updating the OS and developing a killer app.
And if you have the idea for a killer app why would you release or develop it only for Amiga when you could retire happy to a beach on a tropical island if you made it run on a PC?
The Amiga is retro, if you know Amatuer Radio, there is something called QRP, basically transmitted on low power. Whilst the average person will Skype someone on the other side of the world, the QRPer will build a transmitter in a chewing tobacco can and communicate from the woods using a straight key and an antenna strung between two trees. That's the Amiga enthusiast! Yeah I can do that in 10 minutes an an 8 core Mac using Final Cut, but it's more fun taking a few days to do a more crude looking version on video toaster. Because you did it on a computer that makes a mobile phone look like a super computer.
Amiga Inc is irrelevant, they have produced nothing that is Amiga compatible, they produce 15 old Amiga games for the PC and do dotNet development in India. They talk about a redone Tao Intent (Amiga Anywhere) They lease the name Amiga, but that's really it.
