Gruber Reviews iPhone 5S and 5C
Well worth a read. To quote:
With the iPhone 5C Apple may well have created what will prove to be the most popular smartphone in the world, based almost entirely on year-old technology, distinguished only by its colorful plastic casing — yet still sold at premium prices compared to the rest of the industry. Not bad.
And this about 5S:
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.
