In fact actual light mobile devices with touch screen can do the job pretty well, just with some sizes' variation of output screens, displays or powerful projections devices for larger sizes. A synched Kinect with those devices, and it can enhanced a full room (even a meeting room) and there happens a revolution with a whole new real time social collaborative experience (domestic or office)
In fact, to synch "tablets" (from small like iphone, to larger devices) will bring an real simple immersive experience with data interactions. What i seriously believe in, is the incredibly intuitive interaction with the data with some real collaborative display that is "touched" or more exactly "sensed" (kinect like) by more than just a single user at once, a finally real simple whole shared social experience. just Imagine the power of the educative, creative outputs from such collaborative tools. :) Just looking forward.
