To me it would be really nice if my cell phone also had:

am/fm receiver
NOAA receiver
flashlight

Some cell phones come with an LED that can be used as a flash for taking pictures, but it seems like no one thought that same LED might be useful as a light.

More than once I have used the back light on my cell phone as a flashlight. Its not a good substitute but it is something.

I suspect the main reason cell phones don't have am/fm is because it would detract from the services the cell companies charge you $5 a month each for.

With digital TV one would think it would not be real hard to add a digital TV receiver to a standard cell phone, but I am not real sure how many people would find it useful on such a small screen.
