Meh, no. I like the Amiga OS because it's a coherent part of a whole hardware + software system, and the hardware is interesting to play with. x86 PC hardware, whatever its other merits, hasn't really been interesting since the 486 era. When I'm on x86, I'll go with one of the established x86 OSes; when I'm on the Amiga, I'll go with Kickstart 3.1.
