Apple has always been a company more about iteration. I am sure that the next WOW will come soon, but a lot of time passes in between. People are so quick to jump on a different bandwagon that they sometimes forget whats important, functionality. No one does this better than Apple.
People jump ship in the short term, but they always come back. I have a friend in Canada, that upgraded his iPhone 4 to a Note 2, he loves his new device, but at the same time he is just waiting for Apple to drop another gem on him. He says I know i will be back.
