Intel could and does. They make the Mac processors. 22nm Ivy Bridge a few weeks away from retail. 14nm '13... Samsung does 20nm DDR3 and NAND. Can they do processors? Unknown... From what I've seen about "iHeatgate", it is the APU running hot. One solution? Whack watts with lower node. Apple has real serious work to do. 1.3M pixels is just the starting point. Retina draws ~4X wattage of AMOLED.
