Basically an exploration of value. An iPhone can cost 3x times as much as some of these other phones, and is certainly a more pleasant device to use, but does it really offer 3x as much functionality?
The basic (world-changing) functions of the smartphone (location services with GPS, decent point and shoot camera with you at all times, web access on the go, etc.) are present in both devices.
