Restricting? You keep contradicting yourself. It's 'restricting' because you can't add ONE more icon to your dock- yet you're upset that iOS uses the entire screen for icons, and point to the desktop metaphor, wanting almost the entire screen to be composed of a useless background. That's what the lockscreen is for. I've got multiple android devices, and there's nothing more efficient than iOS in terms of getting in and out of apps. iOS5 is jailbreakable- why the hell don't you just jailbreak it again to get the precious 5 dock back? You seem to be bitching for the sake of it, without any real, tangible substance behind the complaints. Just 'it woud be cool to be able to do X, even though I admit X is completely useless'. The sales of iPhones/iPads confirm that most people don't care about this level of customizability, especially when its at the expense of consistency/stability.
