That's a pretty good overview of the Pegasos and Morphos. For "the other side of the fence", look at
http://os.amiga.com/os4/ - there you will find the feature set and screenshots of AmigaOS 4 (currently in closed beta, rumoured to go into open beta in December sometime). The AmigaOne is very similar to the Pegasos, some will argue this but for for all intents and purposes they are the same.
