Were I to suddenly get enough money to afford a tricked out A4000 system complete with PPC accelerator, which I would dearly love to do someday, my biggest question would be on operating systems to run.
On one end, I am of course going to run AmigaOS 3.9 on at least one partition because thats what its built for and all that, and because thats kind of the reason I want an Amiga in the first place, that and the games.
On the other, I'd also want to run a somewhat modern OS so that I can use my Amiga for work and for general entertainment use. Thats where it gets sticky.
You see, my choices there would be either AmigaOS 4 or MorphOS, from what I can gather.
Well, originally, I looked into AmigaOS 4. Now, being on an x86 platform I can't really test either operating system so I can only go by impressions given from reading forum posts or documentation or wikipedia or etc. My original reason for looking into AmigaOS 4 was actually the fact that someone had ported MegaZeux, a program I've been involved with in terms of its community for years, to AmigaOS 4 out of the blue. This brought the OS to my attention and made me think "Wow, if someone just picks up such a niche program and decides to port it, there must be some merit in the system"
I looked into it, and looked into it... The biggest problem for me was the fact that apparently for the longest time there wasn't a modern web browser for it! I mean, gee man, you're positioning this as a modern operating system and you don't realize that 98% of anyone's modern computing is done over HTTP? Then someone made a version of OWB for it, and that quickly became very modern and useful indeed... And then it came down to implementing HTML5's
