Lol, someone bought a 4S :)
I dont think you buy it for the speed increace. Siri would be the selling point for alot, others would be the camera which is better in low light and speed to first shot.
Then again, my 4 takes good enough pics, and the jailbreakers will give me Siri. iPhone 5 for me next year
I'm not sure what video you were watching but it was obvious that he pressed both at the same time. Such a hater, besides people don't buy an iPhone 4s just for the speed difference.
My sister has an iPhone 4 and the speed difference is the same in the video but I'm sure I probably did press my 4s everytime like the video*sarcasm*
