I both agree and disagree.
Will this make iOS much better? Doubtful. I think that we can agree on.
However, let's take a step back here. We've got a fanless chip, running in a handheld device, designed by Apple, that has comparative per-core performance to a mobile quad-core i7. The potential repercussions for this and the sheer limitless possibilities are something to definitely get excited about.
It is my belief that in the next 5 years, Apple computers will truly once again become Apple computers. In-house designed chips. In-house designed pipeline. In-house OS optimisation. In-house hardware. In-house software. And they will completely destroy anything else on the market.
