All i can say is be prepared to be bombared by fans of both sides trying to get you to buy theyre choice =) (the AmigaOne and the Pegasos) personaly i have a Pegasos running MorphOS wich im very happy with

! you could always get WinUAE for you PC and try it out too see if you like the OS? you will also need to buy AmigaOS + get it up and working wich could be more work then its worth for a newbie

so i would suggest to download AROS from
www.aros.org boot the CD and try it out! it will give you a litle idea about AmigaOS + MorphOS! AROS isnt as advanced as these 2 but it will give you an idea.
