Ars Technica Reviews AmigaOS 4.0
Amiga Lover writes "While tales of the troubles behind the Amiga's ownership abound over the last 10 years, work has been going on in the background for newer releases of the operating system that powered some of the most desirable computers from the 1980s. You can now buy brand new Amiga motherboards, and the operating system is very close to a final release. Jeremy Reimer from arstechnica reviews the current developer preview of AmigaOS 4.0, going over this new small and fast OS in thorough arstechnica style."
I always hate seeing Amiga come up on Slashdot. To all you guys, no, it's not dead. It's small and not popular. AmigaOS is to Linux what Linux is to Windows. Remember how many Windows users out there think you're crazy for using Linux and truely believe there is nothing to use Linux for except for server stuff before you post your "Amiga is dead" stuff, as you will be exactly correct as all those ignorant Windows users are in their comments about Linux and Linux users.
Thank you for your respect. And to the article poster, we're not welcome here, please don't bother Slashdot again...
While I loved my Amiga in the day, I can't justify spending $1375 for a G3-800 system basd on the new Micro systems.
This is from softhut, but I don't want to direct link since it is slow anyway:

AmigaOS has had preemptive multitasking since day 1 back in the 1980's.
Memory protection is another matter, it's not there as Linux users would expect it to be, no. It's a highly desired feature of course, but implementing it properly is an issue as it conflicts with some fundamental aspects of AmigaOS arcitecture. We want it, and it will likely happen someday, but current priorities fundamentally revolve around getting the OS ported to PowerPC native and getting it to run on new PowerPC motherboards, porting the 680x0 assembly to C, involving a great deal of "classic Amiga hardware" dependencies, as none of that hardware is present on new motherboards.
Once the fundamental porting is done then it will be time to look at rearchitecting things to allow memory protection, multiple users (it's currently a single-user OS so no user or group file or directory protection concepts). I don't know what all the project managment has in mind for adding such features, but users and developers do want them.
But this isn't what the Amiga was.
The Amiga was a great games machine, with cool custom chips taking the load off the generally-not-too-great CPU, a highly consistent architecture, and an adequate, quirky OS which was good where it mattered for the applications it was used for.
Custom hardware was not something that was seen in commodity PCs at the time. Neither were good quality graphics and sound. It wasn't a better machine. In many ways it was inferior. It was a very different machine, and that's why it suceeded where it did.
AmigaOS 4.0 is simply another OS. Perhaps it's a very nice OS. BeOS was as well. But a nice OS doesn't make it better.
[removed question about true multitasking and memory protection]
;)
Amiga OS had both those in 1985, IIRC.
No, you don't remember it correctly. Amiga OS had true, preemptive multitasking in 1985, but it doesn't have memory protection to this day. Nor does it have virtual memory, or makes any other use of MMU present in every modern processor.
Yes, you could install Enforcer notifying you about writes to system memory, or VMM permitting swapping to disk in case the real memory is exhausted. But both these programs weren't part of system and lost of programs crashed when they were present and running. I remember having exceptions list in VMM longer than... certain body parts of pr0n stars
Other than that, Amiga OS was quite remarkable piece of software at that time with certain solutions still not duplicated in today's operating systems.

from TFA... ...Many people have asked whether or not they can install OS4 on their Macintosh, since both use PowerPC hardware. The answer is no, as OS4 requires a custom ROM embedded on all AmigaOne motherboards in order to boot. This was done under agreement between Eyetech and Hyperion, in order to cut down on piracy and to reduce the number of hardware combinations that Hyperion needed to test and support...
I was pretty interested until I got to that "custom boot rom". Hell, guys, even Apple tossed that requirement when they went to NewWorld.
Severely limits the usefulness of the hardware and software in my eyes. Guess I'm not the target audience then.
