Wireless devices are blurring the traditional distinctions thereby defining a new type of convergence. The software architecture for the new generation of devices should be very different from traditional ones. This paper takes an in depth look the usage scenarios of current and future wireless devices and proposes a hardware and software architecture. Wireless devices are considered as pure access devices without need for storage, display, etc. All the resources are obtained from the pervasive wireless grid - a mix of wired and wireless grids. The resource-rich wired grid performs several tasks like providing structure to stored documents, personalization, aggregation, contex-tualization, etc.
