This is hard to predict. In my opinion the AmigaOS4 looks (hears?

better than the MorphOS. In fact, I think that AOS4 has every chance to be much better system. In all aspects.
Yet, it still isn't freely available, therefore its lacking developers.
In my opinion, we are about to see a situation when better AmigaOS4 is being finally released but it will be a system without support from developers and companies.
Time IS the factor in this race.
