Apple is driven by an upgrade model to buy a new Apple device every three years or so. I disagree. My wife's iMac is 6 1/2 years old, and still gets the latest OS updates (for free!), though we're upgrading to a new iMac soon. My iPad 2 is almost 5 years old, and still gets the latest OS updates (for free!), though we're upgrading to a new iPad soon. It is precisely because our older Apple hardware is still working well, and Apple still supports us with the latest updates to that older hardware, that my family is not only sticking with Apple, but we've recently invested in new iPhones. Apple has earned our trust.
