I liked AROS when I played with it a few times, but found the fragmentation that's happening with the different variants annoying as hell. I found the whole Icaros, Broadway, AROS Vision, AspireOS thing to be a confusing pain, but then again, I'm short on patience. I'm simply used to Linux distro's where I can clearly click on either x64 or 32 bit variants and have the OS burned on a USB key or optical media and installed within 3 minutes. If I've gotta dig around and slog through different variants, I just wash my hands of it, but maybe the download options are more clear now than they used to be.
Are you also annoyed that there's more than one Linux distro? The official AROS website does have links to most of the AROS distros, but I can't see anything wrong with that. Anyway, if it bothers you that much, you can just pretend only one of them exists.
