Limited to my experience? Go on the forums for each and every distro out there. See how many posts there are from people wanting to do really simple things, and the long-winded, sudo this sudo that, cut and paste of commands you will never remeber or know what they mean, editing of Xorg.conf files, kernel options etc..
People without problems don't go on forums asking about stuff. So that's not really an accurate measure of how many people are having success with something.
Linux has many distributions, right now Ubuntu is probably the best for not having to apt get this or that, it has a nice Add/Remove programs application and so on. The only time I've had to apt get something on the latest 8.10 is because I've wanted to do lower end stuff. It also names things logically in the menus in case you don't like stuff like k3b.
Also, arguably pasting text from ubuntuguide.org into a terminal is much easier than going to this website and downloading something, then another to download something else, then another and so on. Right now if you don't have the right codec to play something, it'll prompt you to download them, and it actually works. Windows Media Player tries to do the same thing but it doesn't work. MacOS X still requires you to download the codecs.
As a person experienced with computers, you no doubt assume that everyone can handle downloading and installing stuff. I work in a small office and have a family of luddites to support, and I can assure you that this is not in fact the case. In this situation, Windows or Linux are no different, it's an ordeal to add hardware or software and most of them lean on a family member or heaven forbid call Geek Squad or similar.
Also remember Linux as you refer to it is a large collection of different distributions targeted at many different end users. The fact is, whatever upsets you about Linux could be fixed (may already be in another distro) and is not inherently an issue with Linux but rather a distribution problem. Linux was built by developers for other developers, so it has a bit of a legacy to overcome.
Also, there's nothing wrong with /etc. I know etc contains configuration files and they're all in plain text. If the Amiga had anywhere near the software available or was useful at all as a server, you'd probably have a similar problem to solve there anyway.
If you don't like Linux so be it. To argue it has no advantages over a 20 year old OS like AmigaOS kinda implies you've not looked at the APIs and structures of either OS. AmigaOS is so far behind every other OS out there, it's ridiculous. Beyond that, internally it was built in such a way that improving it to the point where it competes with modern operating systems requires ditching so much of it (and all the legacy code that ran on it), it may as well be a new OS anyway. Right now we have people who can't even decide what AmigaOS is anymore let alone who owns the thing, so don't expect anything to change.
If you know better, feel free to prove me wrong, but Linux's advantages over AmigaOS go way beyond memory protection and it being free.
