When we planned the editorial calendar with the topic ubiquitous computing, we were thinking of ubiquitous computing as the one-to-one ratio of computers to students and teachers and 24/7 access to electronic resources. At the time, we were aware that ubiquitous computing in the computer science field had more to do with wearable computers. Our thinking did extend to small handheld devices as one way to achieve one to one, but not to a many-to-one concept with seamless interfaces that allow for multiple collaborations from anywhere at any time. Our vision has been greatly expanded since our editorial calendar planning took place eight or nine months ago. The reporting from the one-to-one projects in this issue includes examples of collaborative work that take advantage of the wireless networked environment. In addition, Glen Bull and Bill Ferster focus on ubiquitous computing and discuss where the Web is headed with Web 2.0.
