One design element that interested me were the layers of plastics and protectants on the screen. I assumed that a phone without a touch screen would just have fewer things on it.
I was also very interested in the dial buttons both in plastic and in silicon. I have never thought about what the keys looked like in a phone and how they interacted with the circuit board. And I was surprised to see how the keys are thinly laid out in injection molding plastic.
I would say overall that I was surprised at how few parts were in the inner portion of the phone, and how the majority of its volume is plastic. I often think these phones are too light and I assume that the designer made so much out of a light plastic for cost reasons.
