Microsoft has recently published a vision of what they believe computing will look like in 2019. In some ways the way they envision things are really unimaginative (will we really still need a Dial pad and close button in 2019) and in some ways dazzling and exciting.
Some of the technologies demonstrated in the video is indoor GPS positioning, sensor networks, cross-device interaction, the use of pico-projectors, video conferencing. Brownie points for any other technologies spotted.
