As a satisfied iPhone 4S customer, I really don't have a need to upgrade. My phone is perfectly fine and not quite a year old. I have no complaints and it does what I need it to. My previous phone was an iPhone 3G which I had for three years. I don't need to have the latest and greatest device out there. I don't automatically get a new phone every two years. I try to make them last a bit longer.

If my 4 fell in a toilet or something, that'd be a different story. But for now, my current phone works just fine, is less than two years old, and is, $200.00 less of an expense to continue using.
