20-years Old Xerox Report Predicts Devices Bigger Than iPad

Almost twenty years ago Scientific American posted an article of Xerox PARC. Its authors were thinking about the future technology and decided the next stage of it will be the ubiquitous computers.

"Ubiquitous computers will also come in different sizes, each suited to a particular task. My colleagues and I have built what we call tabs, pads and boards: inch-scale machines that approximate active Post-It notes, foot-scale ones that behave something like a sheet of paper (or a book or a magazine), and yard-scale displays that are the equivalent of a blackboard or bulletin board.”

They were right - tabs are the iPhones and iPods Touch and pads are iPads. But does it mean that we can expect from Apple something really huge like big-screen hubs? Such devices have already been developed (the best example is Microsoft's Surface table, the other one is Samsung MultiTouch Board shown on the picture), but they are still too expensive because of a flat-screen TV components.
