Microsoft has published a Mobile PC Development Guide that suggests best-practices for developing Mobile PC and UMPC applications. This sample attempts to use those principles in its design. The main items to consider here are to:

• Make sure the application scales well to the active resolution
• Use controls that work well with both Mouse and Touch interaction - such as using buttons rather than slider controls
• Create controls that are sized appropriately for the display - adding the full-screen ability and making buttons easily targeted with touch
• Think about how the user may be interacting with this application if they are mobile - providing data at a glance and reducing the density of data

Other considerations for power management are to disable CPU intensive functionality if the PC is on battery or if the application is minimized. In this sample, I could have chosen to disable the rotating, animated cube if the application is minimized or not in the foreground. This would reduce the load on the CPU and in turn, save battery power.
