Who cares what others say? Test it out yourself. A x86 is easy to grab, some PowerMac as well (if you happen to not like MorphOS dump it off again to ebay). AROS is freely available, MorphOS Demo as well. The good thing about AROS and MorphOS is that the hurdles to get a 1st hand experience are pretty low and nothing's better than a 1st hand experience.
lol I think Mazze knows that.

Trouble maker.
As for the question. My Morphos box is the perfect size to level my dryer

Other than that who cares. I use them both I however prefer my AROS boxes even tho they aren't as polished. To quote a friend of mine finished OS' bore me.
