Mobile Developer Question:

Scoping starts with a long, hard look at the device. Mobile devices offer different form factors, screen size and resolution, computing power and functionality. They run different operating systems and have other methods of retrieving data such as wifi or 3G.
The challenge is to understand the device and how it will be used to the best advantage: focus on the benefits of the device, such as size and portability, and ensure that the user experience will be optimised.
