Putting MorphOS in the same categorey with UAE is quite a stretch ....
MorphOS runs on its own (the Quark-kernel is just an invisible part).
MorphOS runs PPC-SW written for PuP/WOS, UAE doesn't.
MorphOS has a 100% native OS, while UAE has only a partly native
GFX-driver (which redirected through XWindows instead of going
directly to the HW).
MorphOS has it own native PPC-apps, UAE doesn't.
MorphOS(non-JIT) 68k emu is about 5-10 times faster than UAE on
the same CPU (and the native OS helps speeding up 68k-SW even more).
So comparing UAE to MorphOS is like comparing an A500 to a full featured
Draco (or A4000/060).
