I love my mobile phone. Aside from helping me screen calls and serving as my primary phone these days, it is my lifeline when I'm away from my computer. Most often, its role as my connection to the world takes place when I am out running an errand or away from my hometown.
While my mobile phone is my lifeline to the world, it's very hard to do work on it. Sure, I can check email, review very short documents and manage my blog. But real work is a challenge. Most mobile applications are task-based and focused on providing a single feature very well.
If we want to move past this focused mindset to a world of true productivity, we have to give serious thought to an important question. What, if anything, do people really need to accomplish on their mobile devices?
