Everyone uses their devices for different reasons. Some people use it for contacts while others use it for calendars.
Some people read books on it, and others carry around important documents.
We want to know how you use yours. Please submit an opinion below and share it with our readers. I have a Rim Blackberry 950 Internet Edition with Earthlink service, and it's great. I use it for email to stay connected wherever I go. The service is extensive using the Cingular Network.
