A method of implementing use cases includes associating a use case with each of a plurality of devices capable of being used or accessed by a user. The method also includes providing a plurality of stackable blades, each providing a standard physical interface and being configured to implement a solution to the use case associated with each of the plurality of devices. The method further includes stacking the plurality of stackable blades to form an interconnected stack. Each of the plurality of stackable blades are coupled using the standard physical interface. The method also includes executing a first purpose corresponding to a first use case and executing a second purpose corresponding to a second use case. Embodiments provide an electronic ecosystem featuring ubiquitous connectivity in which a standard contact array in each component of the ecosystem assures interoperability between heterogeneous devices.
