If you need me, you can call me... or can you?

The concept of long distance seems foreign to me now. I've had a cell phone with a nationwide plan for so long now that I forget that some places cost more money to call. I went to give a friend my work number today and realized that she couldn't just call me from a campus phone... because it's long distance. Cell phones are taking over the world, and even many landline plans now include free long distance. So why don't they just get rid of the concept of long distance? ... honestly... money hungry [grumble, grumble]...
