In 1997/1998 before Apple got back on its feet there was huge excitement in x86 land over the impending release of Rhapsody for x86. I remember convincing someone who was thinking about buying a Power Computing Mac in 1997 to buy a PC instead - "Don't worry! You'll be able to run Rhapsody on it!" Now I feel a little dumb.
There are dev releases of rhap x86 floating around (carracho, etc). Apple just never released it. It doesn't matter, anyway, Apple is going with the pp970 not x86...
