Same here, I could survive without it if it weren't a job requirement.
Plus it's nice to have some form of back up plan if I need to reach someone ASAP, to change plans when going out etc. Sometimes people don't read their mail, text messages go through more often/faster.
But since I'm going to remove my battery as often as possible, I'll experiment a bit with how it feels like to be out of the Matrix (funny, they actually use phones to get inside the Matrix in the movie).
