No it didn't because economies of scale took their toll. Still, it would be possible to build an elegant Mac around an x86 processor, but Apple would have to design and manufacture their own chipset. Nothing would make the CPU elegant, but, at least, the rest of the computer wouldn't be this mess.

But then Macs wouldn't be able to boot Windows. When that becomes irrelevant, we may see change.

Minor nitpick: Windows NT has been ported to MIPS, PPC, Alpha and Itanium, and was originally developed for the Intel 860 (though that version was never sold). Legend says there were Intergraph Clipper and SPARC ports too. If Microsoft pulls off the ARM release of Windows 8, that will be one more architecture with a Windows NT port.
