>> The iPhone 5S, released five years later, is roughly 50 times as fast,[1] meaning performance more than doubled each year from that starting point. That may be true, but the iPhone 3G when it came out launched and ran the phone app very quickly and reliably. By the time it received its last supported OS update, it could barely even run the phone app. As a "normal user", my expectation would be that the latest and greatest supported OS for my device lets me run the core apps at a decent speed, and to everything else to be slower. That wasn't really the case during the Forstall era of iOS.
