I can't say I agree there honestly I do use Aros as my main machine. It might be missing somethings compared to Morphos which btw runs great on the emac I just got. However I prefer my Aros machine.
Since the release of Version 2.5 of MorphOS, I've been in exactly the opposite situation. Maybe one day AROS will be refined enough to rely on, but right now I'll stick with my eMac (and I'm looking forward to Powermac support). MorphOS is fast, stable and runs PPC Amiga programs (which you're not going to do under UAE).
Check out the number of posts, MorphOS is by far the commonly used OS for real daily use.
