I wish AROS well, but without official support, I don't see them becoming more than a hobbyist OS. An official Amiga x86 release could potentially be more.
If you think any BoingBall OS is going to make a dent in the desktop market, your in for a rude awakening. Is AROS a hobbiest OS? Sure, right along with MOS and OS4. They are all hobbiest OSs and anything beyond that is mearly an exercise in fantasy or out right delusions.
