The problem is, level-headed as the average Aorg user is, there is still a lot of factionalism even here. The community is not split along community lines but the faction lines set up by the 'players' involved in the Amiga name. The infamous 'Red' and 'Blue' camps - the zealots who see some sort of war between the 'official' AmigaInc and their prodcut (or lack thereof). And the, frankly more realistic supporters of Genesi/MorphOS who can at least buy a vaguely modern computer and OS - and even have a proper net browser from what I hear.
These two camps often also include an overlapping group of even more biggoted user - the PPC zealots, these holy-warriors make it their divine duty to banish the evils of modernity and success from Amigaland by shouting down every attempt to seriously move the platform to x86 and now AMD64. They are pitted in eternal battle with the dread fiends of AROS (who I think need a colour-camp of their own, I'm always partial to yellow in these situations).
MorphOS was probably the best way forward when PPC on the desktop was still around and had a future, since the Apple transition though... Meh. (n.b. anyone who mentions Cell or Wii [or IBM and their customisation hoo-hah] will force me to unleash the terrible hordes of my mutant flying monkeys! j/k) It is still the best developed of the 3 Amigoid clones, but I (and I'm sure a few others) don't want to shell out for obscure hardware to run it. Especially since the cessation of PegasosII production; Efika just doesn't set my heart a flutter. So to speak.
AROS at the moment also has very little future, it has the most potential of the 3 clones but until the devs get some serious organisation and shake things up they're never gonna win over the community at large. They may have no schedule, but I don't see 'em rocking. They need a Linus Torvalds type character, a benevolent dictator who rallies the troops and gets them to produce.
OS4 and Amiga are dead in the water frankly. They have shown the world exactly how NOT to run a company, The OS Hyperion delivered doesn't really seem to do anything that MorphOS doesn't, less in fact as you can't seriously browse the net yet. The boing sticker doesn't really mean much to a lot of people anymore, No one who ever made Amiga great has anything to do with the current incarnation of Amiga. I'd rather buy a computer from Irving Gould. At least he knew to hire someone competent to make the money, then fire them and do a runner.
The classic scene is I think the only one that people can still rally around. It is unassailably Amiga. It has the most activity going on at this time, and unites both those seeking a retro 'fix' and those who realise that you don't really need a 12GHz septupal core Intel Core15-Ultra-Mega-Overheat to do a bit of word processing, artwork or use a spreadsheet. Projects like the MiniMig, Clone-A, the AROS Kickstart replacement, Motorollin's 3.9 ROM hack, lots of interesting projects that don't concern themselves with the tech race. Which is nice.
