Very true, klx300r -- may I call you "klx?"

-- so the question is, what niche does the Amiga best fit these days? And that answer is pretty simple: nostalgia. That is the market that is most likely to generate the most revenues and allow it to expand, not some expensive and doubtful architecture in an already mature and crowded industry.
As to MOS, well, I'm more likely to buy it than OS 4.1 because the cost is much less. But, then again, I'm also more likely to wait for the PowerMac G4 version, since those are even cheaper.
Regarding AROS, well, the box I'm typing on runs Win7, OS X, Linux, Amiga on Linux and AROS and it didn't cost me a huge amount of smackeroos just to get any one of them. As to people running to it, well, AROS is still a bit rough around the edges, so, no, I don't see people "running" to it just yet. But I do watch the development of the iMica and the AresOne with interest.
To be honest, though, AROS suffers from the same problem that most open source software does: always behind everyone else and in AROS' case, WAY behind everyone else. Which is why I'd love to see a professionally developed version available and why I'd like to see OS 4.1 on x86 and why I watched Anubis with interest. (It's a shame that it appears to be stillborn.) But as long as Hyperion remains fixated on PPC, I'm not spending my hard earned money on it, not solely for nostalgia's sake.
First rule of business: understand your niche and exploit it. Hyperion doesn't seem to know it. Instead, they're selling to the religious, not to the regular guy. I believe this is a dead end.
