Same, never seen AROS outside a virtual machine to be honest. I used to believe in its future but nowadays I`m not so sure, seems like it`s begun to fragment or is close to doing so.
The only other real option (besides MOS of course) is, in my opinion, Amithlon which is still pretty killer even today.
Sorry for inserting another off-topic post in this thread lol :o)
