Sense

1. Over-blown visuals.
2 .Neglecting technological limitations, such as slow Internet connection, slow processors and single-threaded OS architectures.
3. Confusing navigation (flow, layout and taxonomy).
4. Confusing the iPhone with a computer. Neglecting to use new iPhone interactions (fingers instead of the mouse; multi-touch gestures; turn, tilt and rotate) and technological features such as phone functions, built-in GPS and accelerometer.
5. Disregard of context. A lack of understanding of how, when, where and why the mobile device is being used.
