I can not talk for the others. I bought a Pegasos to be able to run my old Amiga programs and the new Morphos programs. I'm using an Amiga since 1996 because my AppleIIGS with GS/OS was dying. I'm using a Pegasos because I don't want to use mainstream OSes and PCs and I also want to be able to experiment with this machine.
So I will also install Debian and MOL on it because it's fun.
So Vincent, don't be so angry and let people do with their machine what they want.
