Dean Bubley addresses the challenges facing innovators looking to create openness and choice in the mobile communications market. Bubley, an analyst specializing in the field of mobile and wireless, reminds mobile communication innovators who hold a Utopian view of openness that they must consider the constraints posed by regulations, laws of physics, commercial practicalities, and especially the psychology of the Normob, the normal mobile user, who doesn't care about openness and will need to be convinced.

The economic realities of hardware development often stifle innovation. Peter Semmelhack, CEO of Bug Labs, discusses a change in approach, similar to the open source software model, that will promote innovation in the hardware space. Based on the Lego model, Bug Labs is creating a set of tools they believe will eliminate some of the cost and creative prohibitions, and enable a community of users and developers to experiment with the creation of new gadgets.
