We are in a very difficult situation: On x86 we have to compete with Windows, MacOS X and Linux. AmigaOS can't do this without so many changes, that almost nothing of the original AmigaOS would be left. That would mean we can use as good Windows or MacOS X with UAE for playing old games.
As a niche platform Amiga needs own hardware and software. 1. 68k and PPC is dead. 2. There is no need for another desktop-computer besides x86 with Windows or MacOS X. That's why Linux is not the "number 2", even if it's free and a lot of good software is available.
So what niches are there? Mobile phones? Handheld computers like the Pandorra or the EeePC? Settop-Boxes? Game consoles? Very cheap computers? All them? Yes, that is maybe the only left market except emulation of classic Amigas. And for that devices there are two possible CPUs: Coldfire or ARM. The advantage of ARM is, that we are not depending to only one manufacturer. What that means we saw with Motorola/Freescale.
So if I had to decide, AmigaOS 5.0 would run on ARM! And that is the other point: There is the need for one strong company (or movement) to take in into one direction. There must be one official AmigaOS, not "hundreds" of small projects of keeping "the spirit" of AmigaOS alive.
