It doesn't hurt the battery or affect charging time if you don't run it down, but running it down till it shuts off helps to calibrate the little computer chip in the battery so you know better exactly how much battery life is left.

Apple recommends doing it once a month, also any time you charge it, letting it sit in the 100% charged state for at least 20 minutes or so will give you more battery run time. It does a trickle charge sort of thing at the end.

BTW when you run it down till it shuts itself off it takes a few minutes, 5 or so, to turn itself back on. The battery needs to get to a certain charge level before it will reboot.
