The document discusses the transition to the "post-PC era" as computers and devices become more ubiquitous and integrated into everyday objects and environments. It notes how Marc Weiser in 1991 envisioned a taxonomy of tabs, pads, and boards to describe different types of emerging computational devices. Today's devices are described as networked, context-aware, data-collecting, sensor-powered, and often multi-purpose in ways that were not envisioned just a few decades ago. The document argues that as our tools and devices shape us, the many computational objects being created will in a sense become extensions of ourselves, forming a new kind of distributed digital consciousness. It closes by stating that in designing for the post-PC era, the
