IMHO opinion this whole discussion about OSs is moot.
Ultimately we all want the Amiga platform to reclaim its legitimacy in the public eye.
This does not come by selling a hardware agnostic OS like Linux. It comes from having a BOX like a Mac with a big bold AMIGA logo.
If this were not the case we'd be happy with advancing the OS UAE uses. Or we'd be seriously going with AROS and not discussing this any further. Amiga Inc even realised that hardware agnosticism will be selling the Amiga platform short and got hardware deals going.
But we're all sitting around waiting for what?

An AMIGA BOX!!!!
The Pegasos BOX is out and not everyone is buying it, so what does that tell you. ITS STILL NOT AN AMIGA BOX!!!!
As stupid and as crass as it sounds having an Amiga is akin to making a fashion statement. AMIGA is the label.
AND YOU DO WANT THE LABEL. ADMIT IT!!!!
See my avatar. You're already reacting emotionally to it. Notice it does not say Pegasos or Genesi.
