Pantech G-3700 slim clamshell with slimmer secondary display

At a time when many clamshells offer secondary displays that offer resolution that would have been reserved for primary screens in earlier models, what has Pantech done with its G-3700? It's gone retro, with a one-line OLED that gives you the bare minimum (date, time, Caller ID) in a display that is actually on the lip of the base, rather than on the back of the top panel. Other than being able to see the display whether the phone is open or closed, we don't see a whole lot of value in this, though if it contributes to the phone's slim profile (0.59mm), it's all good.
