The best thing OS4 followers could do to stop worrying about the future is switch to MorphOS and enjoy it right now

OS4 is apparently no longer developed as it has not received real updates for ages, just empty promises and ultra-expensive/ultra-slow hardware.

The only thing Amiga OS4.x could offer to MorphOS is the Amiga name. Ben Hermans usually sues his partners so I don't think doing business with him is a good idea. He even stole AmigaOS from Amiga.

If I wanted to use Gallium, QT, shared objets, UAE and a fancy desktop I would use Linux and everything would run much better than with half-assed quick ports of linux CLI tools, slow x11/qt apps that don't integrate nor share amiga phylosophy or slow browser.

OS4 is a worthless try to reinvent the wheel with a square result.

Collaboration with AROS makes sense and is already done from time to time but collaboration with something of low quality that tries to mimic linux is not something any amigan would desire, unless he has been brainwashed to think that linux is amiga.
