Well, Wouldn't it be smart for Microsoft to jump on the PPC-technology now and start to write a OS that can be run on any PPC-based motherboard? Making own os/program to the x86 they already can and making own program to the PPC they also can, so making a OS for the PPC shouldn't be so difficult for them?!
Where Apple leaves the PPC-customers, Microsoft could continue to support them?
Yeah I know, I don't like Microsoft either, but hey! I really need that PC for surfing the web and for example making cds easy.
