Like many others on the East Coast, I spent my lunch hour going through the various computer industry liveblogs of Apple’s iPhone 5C and 5S launch event.

While many of the things we heard about both devices were covered extensively in various leaks and analysis in weeks prior, by far the most the most important new thing that was announced at the event was that the iPhone 5S uses a 64-bit ARM chip of Apple’s own design, the A7.
