I've owned a Pegasos MOS1.4 system in the past and it was quite amazing, I'm sure 2.0 is pretty sweet. However, 2.0 on the Efika seems to have it's drawbacks such as no sound support yet. IMO (YMMV and some will hate this statement) MorphOS is a better, more compatible product overall and it is available with hardware NOW. If and when OS4 is ever available again for viable hardware is a very big question mark.
