Which kind of “openness” do you want? http://oreil.ly/bGQcZU Google’s or Apple’s?
Apple controls the iPhone, iTouch and iPad experience by allowing or disallowing applications in the store. Some call this a closed system (and it is) but it does lead to “computers you can’t break”, which is what most (non geeks) want. That’s what I want for my mother! (It’s want I want for my car too. Cars were once prone to breakdown and you needed to be a mechanic to operate one.)
Google controls the data “in the cloud” for most of its applications. That’s just another sort of control and in many ways less open that Apple.
Which type of control do you prefer?
