I'll start the ball rolling with this one, as I'm sure others will be able to provide more instances:
True, segregated multi-user support.
I don't care, I'm the only user.
Firewalled TCP/IP stack that is built deep into the system.
Windows by default firewalls only one of incoming or outgoing traffic, forget which. You'd be mad not to use a third party firewall AND anti-malware suite. Even without a firewalled TCP stack your risk of malware IN REALITY is less with Amiga than Windows. Yes its security by obscurity, but it works. In THEORY, yes Linux and OS X are more secure by design, but in REALITY, if there was enough motivation malware could be as damaging on Linux and OS X. So a significant part of Linux and OS X security is obscurity as well. There is no 100% secure OS
Full memory protection. OS4 redresses this somewhat, but it's not nearly as effective as in the others.
There's a whole thread on MP, and its nowhere near a big deal for most users most of the time. Yes a system with MP is better than one without, but in REALITY, the lack of it hasn't made Amiga a perpetually crashing mess. As I've said earlier look at all the software-apps, utilities, drivers written, and then all the art, music, video, documents on Aminet as evidence as to how well this system without MP works in practice-you couldn't do this if software kept bringing the OS down and people kept losing their files!
Fully functional network file sharing.
Yes
A HAL worth a damn.
Yes, but a lot of nice third-party Amiga hardware seemed to work fine anyway. Anyway, whats CGX/p96 and AHI?
SMP
yes.
As for the restriction on apps. Many users might well argue that things such as iTunes or WMP represent core functionality within the OS.
Equivalent media player software is available as open-source alternatives, and if you could get AmigaOS to run on fast enough hardware you'd have similar functionality. Its not the OS stopping someone porting a general media player, the codecs are all out there. Having said that iTunes runs best on Mac. Linux alternatives have issues with some iPods anyway. But I was interested in core OS functionality, not apps. Everyone knows Amiga has far less developers willing to write software for it.
Apparently you didn't get what I was aiming at.
I wrote:
You put in 20, 30 plus patches into a 3.x system with all the trimmings
Apparently you didn't get what *I* was aiming at. Amikit is good example of exactly that and as far removed from a 3.x system as you can easily get. And guess what? Most apps that i have tried work as well as they do on a vanilla 3.1, and i can *still* work my around it to troubleshoot.
and suddenly one of your favourite apps stops working.
Good luck trawling through it all to find out which one of those patches (or if you're especially lucky, combination thereof) is the culprit.
Even worse is the last three kernel updates I've done with Ubuntu through the repo's and I end up at the grub prompt!!
What you say is possible with any OS, and when it usually happens after the last patch/addition you made. The point is when it happens on Amiga, its usually something that starts from user-startup, WBstartup, changes a shared Lib, or executes something in C. I have more hope in tracking it down than I do Win 7, or Ubuntu.
Been there, done that. Wasn't fun.
Quite.
