New Rules ...

• Location aware
• Motion aware (translational + rotational accelerations)
• Information aware (WiFi, free + 3G/4G, cost)
• Battery aware (~10+ hour working day)
• Gesture aware, all of which means:

The app must be a different beast from the Application

• Software which largely relies on mouse/keyboard has to be refactored for touch
• No Java, Flash (at the moment)
• JavaScript/HTML5/H.264/WebGL instead
