I have over 100. Most are family, some are work-related, and of course, friends. Then there are the local businesses I deal with all the time, as well as utilities and bills I pay on. I also have my Doctors' numbers in my BB. Saves me the trouble of having to hunt for their numbers when I need them. The total number of contacts changes from time to time. I've also got a few Crackberry friends too.
The world gets smaller daily thanks to my BB...
