If you are looking at AmigaOS 4 as a serious alternative to Windows/MacOS/Linux: then granted. People are not. But if we look at it as a hobby then money is less of an equation.
In my case it is not quite so simple and possibly even the other way around.
I used to use Amiga everyday, "as a serious alternative to Windows/MacOS/Linux". That is to say that, whilst I used it mainly for a hobby (recording music) I didn't use other platforms much at all. (I also used Amiga for all my email / browsing / university projects / etc.)
Back then, I would happily spend over the odds on Amiga gear as, even though it would be more expensive than comparable Win/Mac kit, it did everything I needed and was nicer to use.
Now I no longer use Amiga as a serious alternative to Windows/MacOS/Linux. They are still nicer to use but no longer do everything I need. Music software on the Amiga began to stagnate and I gradually started using Macs, to the point where I stopped using any of my Amigas for music at all several years ago.
Nowadays when I switch on an Amiga, it is not so much to pursue my main hobby (I didn't even bother with speakers the last time), more the Amiga *itself* being a hobby.
For this particular hobby, I'm much less inclined to spend over the odds.
Having said that, I still like using the system for it's own sake and can still occasionally be persuaded to part with some money for Amiga goodies but the amounts I'm prepared to part with are proportionally much less than in the good, old days.
