With the delays to x86 (Broadwell, Skylake) I don't see how they can completely abandon ARM. Is Microsoft really doubling down on Intel now? Do we really think x86 will ever overtake ARM as the de facto mobile platform? Just because Microsoft's ARM-based products are all flops doesn't mean ARM is dead for other manufacturers and software makers. Anyone care to fill in some blanks for me as to why Microsoft is so embolden now? What is Intel up to?
