There is a mobile war brewing among industry heavyweights that is pitting Android (Google), against Windows (Microsoft), Symbian (Nokia) against iPhone (Apple). While on the surface this stiff competition appears to benefit consumers, for developers it's a growing nightmare to build applications that run on these different operating systems and try to maintain some degree of compatibility and interoperability. The problem intensifies when you consider applications should ideally span not only phones, but MIDs, UMPCs, cars (telematics) and other embedded and wearable computing devices. Pervasive is the new Mobile. A single platform that spans all "Screens of Life" would truly be something to behold. This paper discusses some of the challenges and trade-offs developers must make and highlights one solution to overcoming them.
