It reminds me of this: http://apc.io/ http://apc.io/ At some point, we have enough power in a small space that the hardware powering your computer or laptop is basically the size of a credit card and it doesn't matter if it's ARM or Intel. Apple can save money and get better battery life by making their own chips (as they do in phones now) so why not move that up the hardware food chain once the performance is "good enough". Apple is about selling mobile devices to consumers and probably the #1 thing the average buyer wants is longer battery life, even at the expense of performance. Also, Apple knows the power of controlling their own destiny and inevitably when they partner with a company, the same company tends to turn around and resell the innovation as their own products - Microsoft Windows, Google Android, and Intel Ultrabooks. Apple is big enough now they might not need to partner for such innovations much longer. That could lead to an even bigger and more sustainable competitive advantage.
