I use mine for both work and pleasure. Calendar and viewing documents comes in handy. Unfortunately, my company does not allow me to be connected to their server...yet
When I got my first Blackberry (Nextel�s "Blue Berry" ha ha) it was strictly for business. But every time a new one came out I had to have it. Now I use it for personal and work and I don�t know what I would do without it!
I was a palm Pilot user waaaaay back. Then they came out with the Kyocera 7135 (bet nobody here remembers that thing) which was a phone that included the Palm OS----HUGE, but very cool to have both things in one device.
Mostly personal and I couldn't live without it. It keeps me in touch and organized (at least a little bit anyways). Poor little thing never gets a break from me!
All pleasure for me. I'm always up to date on movie times, game scores, and whenever there's an argument in my group of friends (often happens with 19-21yr old guys...) then out comes Google to prove everyone wrong exvept me.
And of course the GPS is always a nice feature, I sometimes need to run errands to parts of town I don't have memorized.
Both. I use it for business but even if my career path would change and I'd go to a field where the blackberry service was not needed, I would still be faithful to RIM.
