Last year Apple released two new phones instead of one with the iPhone 5C taking over as the top of the line along with the 5C as the low cost phone instead of just moving the iPhone 5 down to $100-with-contract spot.
The 4S then slid down to be the free-with-contract phone which meant Apple was competing at the low end of the smart phone market with a device already two years out of date.
For customers it meant their brand spanking new phone will be four years out of date by the time they are eligible for an upgrade.
With the introduction of the iPhone 6 and iPhone 6 Plus yesterday, last year’s 5S and 5C move down to the cheep and free price points. Both the 4S and 5 are gone with the oldest iPhone in the lineup only one generation back.
