John Gruber, to no one's surprise, reviews the new iPhones. Of course he loves them… If I had one, I'd love too it since I love my iPhone 5. Among the details of fit and finish, he talks things only geeks care about: speed benchmarks. Now we all expected the new iPhone 5s to be fast, but this was eye opening:

To put that in context, the iPhone 5S beats my 2008 15-inch MacBook Pro by a small measure in the Sunspider benchmark (with the MacBook Pro running the latest Safari 6.1 beta). The iPhone 5S is, in some measures, computationally superior to the top-of-the-line MacBook Pro from just five years ago. In your fucking pocket.

Emphasis mine.
