Not to mention MorphOS flies on a PPC Mac Mini! It also flies on my MDD 1.0 ghz dual G4. I am interested in OS4 like skins for MorphOS though, that sounds interesting. Still I voted yes anyway. I already have OS4 on my Sam and reg'ed MorphOS on my mini and I'd probably still buy OS4 for one of my PPC macs if someone finished the port.
