interesting to see this area of the smartphone marketplace, as opposed to OEM or OS market share by units. apple definitely has the upper hand in that it owns the entire vertical, from the iOS software to manufacturing the phone itself. furthermore, apple, having planned extensively what will go into the phone, is able to bargain for cheaper raw material costs, thereby increasing profit. not only does apple know how to dominate market share in iphone users, but also they know how to make incredible amount of money off of that segments business.
