Yea, AROS is still pretty green. The core os its self is pretty solid and mature at this point. What's needed is drivers and apps ( and a better installer! ). Aros is far from dead though, the developer mailing list is rocking.
The average user probably won't find aros that interesting but keep checking back every 6 months or so, eventually you will find it in a state thats quite useable.
A descent browser port would probably increase the aros community by a factor of 10 in a short ammount of time, and it's only a matter of time until that happens.
