187 mobile professionals gave their views on how they use mobile devices, applications and services. As well, I asked questions about the scope of potential new applications of interest to them.

Group call. Imagine that you get a message on your cell phone labeled ‘Manager’s Group Call’ and as you accept the call, the system plays a message from her that there is an emergency board meeting and she needs you to participate in a conference call right now.
