One of the more interesting predictions:
"Picoprojectors are a nascent feature addition to smartphones. Although very small in number, this category promises to create higher multiples of traffic due to the high bandwidth required to project images and videos from an advanced mobile device."
I'm not so sure, though. Will picoprojectors really change consumption habits that dramatically?
