Let's say it's been twenty years since PDAs have been widely available. I returned to higher education less than ten years ago. K-12 seems to have embraced learning technologies, and their affordances, to improve primary and secondary education. In my experience, few educators with terminal degrees have made the effort while younger and more precarious teachers are slowly adopting educational technologies. Administrators are leading the way with their digital management systems and students are using proprietary social media platforms. Our institutions are doing what they were designed to do: resist change and reproduce the social order. Research paid for with public monies is as quickly privatized as that produced in corporations. Open education practices are just beginning to be explored.
The first PDA, the Organizer, was released in 1984 by Psion, followed by Psion's Series 3, in 1991. The latter began to resemble the more familiar PDA style, including a full keyboard.[4][5] The term PDA was first used on January 7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevada, referring to the Apple Newton.[6] In 1994, IBM introduced the first PDA with full telephone functionality, the IBM Simon, which can also be considered the first smartphone. Then in 1996, Nokia introduced a PDA with telephone functionality, the 9000 Communicator, which became the world's best-selling PDA. Another early entrant in this market was Palm, with a line of PDA products which began in March 1996.
