But then there's also ARM and its slow crawl to replace x86, mainly in areas x86 didn't have much luck in capturing (mobile), but which now is increasingly making its way into nettops, and undoubdedly will eventually start to tackle high-end personal computing. In other areas (such as GPUs), vendors frequently toss support for features deemed obsolete (though many of them remain support in drivers software paths, just don't use those features cause the speed sucks).
