Know thy history!
“This work is a historical study of the Dynabook project and vision, which began as a blue-sky project to define personal and educational computing at Xerox PARC in the 1970s. It traces the idea through the three intervening decades, noting the transformations which occur as the vision and its artifacts meet varying contexts. The dissertation was for a PhD in education; the focus of this work is mostly educational, though I’ve tried to do justice to the technology throughout. I defended it successfully before a committee of profs from education and compsci on Halloween 2006.”
