Now I imagine a brainstorming session at Apple a couple of years ago;
Jobs: Ok, we are going clockwise, start.
Engineer1: We should use a 5" screen in the new iPhone 5, Samsung will go 5", and it even has a 5 in the name.
Jobs: Why the hell should we do that, just because Samsung is doing it?
Engineer1: To improve user experience for using the internet and watching media content?
Jobs: I don't see where you are coming from, why wouldn't they just use their iPad or MacBook for that?
Jobs: Next!
Engineer1: But, but ... some of them don't ...
Jobs: I said next.
Engineer1: Ah, nevermind.
