All three seem "Not Ready For Prime Time".
However, that said - Morph OS seems to be ahead in developement than all the others. So, it would be my logical choice for a winner.
As for OS4, well, we'll see. I will count my chickens after they hatch. Looser of the moment - ie. not available.
AROS - to me AROS is not even a complete OS yet, but it is really fun to play with. And in the future as it is developed may become the choice over all because of open source. A real community project rather than a pure business venture. Just wish I was a coder, as this is where I would be coding. I have a VIA ITX mobo and am in the process of making a custom AROS box. That is my faith in the project's future. What fun it is. :banana:
