You guys realize the iPhone is fast because it runs an extremely basic OS right? Hell even increasing screen size would slow it down I bet. Put android 4.2.1 on an iPhone 5 and let me know how fast it is.

That's totally false. The iPhone 5 runs iOS, which is based on OS 10's Berkeley Mach kernel unix. It only takes one google search to find out facts, calling iOS basic is just ignorant. That same google search will tell you that the iPhone iOS and custom made chipset is heavily optimized for gpu operations. Another reason is that Apple took four years to hand-draw the entire wafer. Four years of painstaking manual engineering. The iPhone is fast for a reason.
