Very much agree about the openness argument. Though, speaking to the quote about teens and prediction, I present this:

This is what Motorola and Google and Samsung and BlackBerry and everyone else, with the sole exception of Apple, do not get about “open” computing. It’s powerful, but for ordinary people, it’s too powerful

Notice a prominent name missing from that list? If what the author feels is true (and being a teenager himself), this speaks volumes to just how far they are behind the curve.
