What exactly did you mean?
Hem, I think he meant most amiga-users actually neither tried an alternative, nor desired to do this anyway, so they can't understand how much those 'alternatives' are good and tied to the original good old AmigaOS spirit.
And, I can add, sometimes they prefer reiterating the same objections forever, independetly from the reality. For istance, I read here that AROS is still "useless" while I have it installed on a PC I can actually use for coding, reading emails, chat with IRC, play MP3s, MPEGs and AVIs, paint something with Lunapaint and, hopefully soon, browse the Internet with Traveller. Which is not so much, but it's pretty more than "useless" and fairly promising for the future. In order to show what's exactly the point reached by AROS in the latest weeks, I've just released a new beta version of my VmwAROS distribution,
www.vmwaros.org. Sorry you need a fluent PC with at least free VMware Player or Served installed on to test it by yourself.
Some months ago I saw MorphOS running on a Peg and it was quite good. However I'm not a big fan just for the same reason I'm not so fond of AOS4 either: they are old-age ideas sold to you as like as they were revolutionary products. And the day you have to pick up your money and give 'em to anyone, you like the idea they will come back someway by using the product you're buying, and this is not the case for AOS4 and MorphOS. That's the main motivation why I think Amiga should naturally go for a completely Open Source way, and AROS is the only one. I don't spend money on it (well, not quite exact: I've spent some money on bounties, but I've quit drinking beers in pubs after marriage ^__^), so anything I do with it, even only amusing myself, is well accepted.
In the end, I see AROS, MorphOS and AmigaOS4 as three faces of the same concept, so I prefer looking for what unites them, instead of what divides.
Cheers,
