AROS is to Linux alike in thinking. I think that Amiga users are dedicated users. It means that they love to be a part of a community. AROS dosent create that community, it tries to open it and make the Amiga community as loose as the PC community.
AROS is in current active porting to EFIKA and x86_64 with a hope for ARM in the future. EFIKA maybe a winner for Genesi, however I don't see Peg3 going anywhere. If the desktop doesn't have bang:buck ratio of AMD64, you better have an amazing perk (like EFIKA) or show me a sub $500 notebook/subnotebook. Othewise your just wasting people's time.
As far as AROS not having a community, don't tell the folks on
AROS-Exec.org that. Else they will mock you for not having a clue.
