I'd like to know why people using AOS 3 doesn't jump on the AOS 4 train? What is holding you back exactly?
You are saying "jump on the OS4 train" like it would be a natural thing to do for everyone. But it isn't.
Well, in order to make my point I'd like to start with a short summary of the Amiga evolution past OS 3.0:
1992 – Amiga OS 3.0 is released
1994 – Commodore stumble (and eventually falls in 1995). But they manage to get Amiga OS 3.1 in various ways, and distribution was further formalized by Escom when they took over in 1995.
1995-1996 – In the shadow of Commodore’s bankruptcy, a community driven effort to create an Open Source version of Amiga OS is formed; the
Amiga Replacement Operating System (later “Amiga Research Operating System”, and even more later simply “AROS”). First AROS release announcement on usenet is from Aug 1996
1999 – Haage & Partner/Amiga Inc releases a new version of Amiga OS which contained many of the “hacks and patches” that most Amiga users had had to resolve to in order to get their Amiga’s to function in a more modern way.
2000 – The first public version of MorphOS is released for free download. It ran exclusively on Amiga’s back then, but the target was set for the upcoming Pegasos PPC computer.
2000 – Later that year a new version of Amiga OS is being released by Haage & Partner/Amiga Inc.
2004 – Hyperion releases the first “Pre-Release” version of their OS4.

Today and the future – We now have 4 different operating systems that people in the community uses daily; Amiga OS 3.x, AROS, MorphOS and OS4.
OS4 is PPC only, and Hyperion representatives has on numerous occasions publically denounced any kind of port of their OS to a different architecture than PPC. MorphOS is also tied to PPC, but nothing has been said about future migration. AROS is multi-platform and open source, which seem appealing to some.
But you can’t forget the fourth (or should I say *first*?) platform; the original (real) Amiga! And I think you could draw a line between this one, and the other three, since the other three is about SW only, while the first one also weight heavily on Amiga hardware. Enthusiasts of this flavor has continued to improve their OS in various ways (like we always did), and AROS is already helping somewhat here, and will continue to help even more in the future. We can call this branch "Amiga OS +", or why not "
AOS+" or similar, in order to *not* breach anyones Trade Mark IP. Its about evolving the 68k Amiga OS.
In addition to Individual Computers (and others) efforts of bringing new technology standards and interfaces to the Amiga computers, there are also Various interesting HW projects are being made to *reimplement* the Amiga (like Minimig) and also *improve* it and *evolve* it (like Natami). These are real Amiga's, *not* in name only (in fact - not in name at all), but in *technology*.
And which one of the OS flavors will be of interest to these Amiga enthusiasts?
Well, from the Q&A section of Natami:
Q: "What operating systems will the Natami support?"
A: "Our target for supported operating systems are exclusively Amiga OS and AROS. All the clever features of the original Amiga hardware and Natami hardware can never be properly used by Linux."
So they want an OS that *fully* makes use of the new (and existing) Amiga hardware.
And no – "Amiga OS" does *not* mean OS4, for obvious reasons. Hyperion’s OS4 isn’t even on the map for these people,
it couldn’t be more irrelevant. What is relevant is to continue to build on and improve the Amiga OS that works on real Amigas!
Hope you understand better now.
