I keep in contact with several organizations through email and having it mobile so I can keep up to date through out the day is invaluable. Before I had my smart phone I had to block out time while I was at home for email which affected my family time. I can also quickly get answers to questions immediately instead of waiting until I get to a computer to get the info. I look up address on maps, navigate to places I have never been, etc. If you are any type of data consumer I would bet money you would quickly find a smart phone invaluable.
