He he, this is probably not the list that the previous poster wanted, but these are the advantages I see.
The CD ISO images boots on any intel box I ever tried it on, and that's a big advantage to me here. I don't know anyone in the US who doesn't have either an Intel box or is on a MAC. Whether that intel box is running on linux, M$, or something else the CD still boots, making it an Amiga-like OS machine. Just think of all the people who might like it see it an run it.
That's an advantage over a PPC based machine because I don't have to go out and buy new hardware. Aros runs on a bazillion computers already in place world wide.
Very few people would go out and buy a new box here just to run another OS. PPC motherboards aren't mainstream, but intel boards are. That makes the target market for an Amiga type OS very very HIGH, cause just about anyone could run it, and the ISO performs extremely well everywhere so far (even on low CPU power boxes).
So what advantage indeed does Aros have? Well you don't have to wait on someone to buy a new box to be able to use it. It's sheer numbers on it's side..
It could be a revolution..
