People write everything from quick memos to novels on their phones.
I like to use mine as an idea notebook while out running errands or jogging in the park. I can write notes, take pictures, draw, or even record audio or video if I want.
Phones also function as social media networking devices. While it can be a bad thing to be bombarded with information 24/7, having the option to check a product or update personal Web information away from the desk is important for many individuals.
