I was watching the WWDC 2013 Live demo and I noticed that their demos included iOS 7 that was at ridiculously fast speeds. It kinda gives me false hope that iOS 8 will somehow be that fast. Not complaining about the features or the OS itself but I really liked the fluidity and responsiveness that they demoed in the product. Why is that it's super fast in demo but the speeds aren't up to par at the moment?
