AROS is the only part of the Amiga scene that has much hope for forward development.
It's the only option that doesn't require overpriced, undersupplied, and/or obsolete hardware, and it has the openness and transparency that a niche OS needs in order to maintain it's fan/user base.
And there is a niche to fill. Every major modern OS is bloated and bogged down with features and code that most users will never even need,
There's a place for a lean, simple, easy to use OS that takes advantage of the power offered by modern hardware. AROS certainly isn't the only candidate to fill this role, but it's the only one I can think of that has a significant pre-existing fan base, i.e.. Amiga enthusiasts.
It also helps that it's free and can be sampled from a live cd, and without any investment in hardware.
