You know, a cell phone doesn't need to have a fancy touchscreen or a slide-out QWERTY keyboard to be slick looking. Simple design is oftentimes just as good, if not better, than complicated, flashy design. Just take a look at this LED cell phone, for example. It doesn't even have a screen, but it outclasses many of its rivals through sheer simplicity of design.
Simply covered in lights and touch sensors, the phone uses a tiny amount of energy and is completely efficient. Its simplicity and efficiency make it perfect for developing countries, as it can be loaded up with simple AA batteries rather than with Lithium Ions that would need to be charged frequently. No word on this concept becoming a reality, but keep your eyes peeled.
