With MorphOS there is very little need to use UAE, except for nasty hardware hitting old applications. There is a UAE for MorphOS, but you'll find most applications either have a MorphOS port or run very well under JIT of the 68k. For instance, IBrowse, FinalWriter, and ImageFX work lightning fast under JIT. Amiga apps that have become MorphOS apps include fxPaint, Voyager, YAM, and fxScan.
(the JIT of the 68k is invisible, and every application including the 68k ones effectivly run as native applications to MorphOS)
