MorphOS is way ahead of any and all of the competition in the Amiga field. And MorphOS is the only one that has shown an ability to move Far Forward Fast (relatively speaking)! Not open source, so its development is entirely controlled by the development team. OTOH, open source isn't necessarily the best way forward; it could very well mean very slow and unstructured development in an anarchistic way with no goals. That's not good, if you want "the best way forward".
Agree, it is way forward.
But picture yourself 50 years forward. What are you gonna run then, 55 year old Mac with MOS or latest mainstream architecture with AROS, wtf,,, 50 years from now, AROS might just become very usable as a workstation (if the concept of a workstation computer is still around then).
