Wearable displays - surely the way of the future!

Here is an article from Engadget about how the military is
using wearable, see-through displays.
I truly think that one day everyone will have a pair of
customised glasses that will do all sorts of things for them
including being a display for any device that they access.
Maybe just have some touch link to choose the input source.
(you don't want other people picking up your source)
(well, only when you wish it)

Air Force taps Microvision to develop wearable displays

HMDs may be slow to catch on with the general public (despite some companies best efforts), but the U.S. Air Force certainly seems to be sold on them, awarding Microvision a $3.2 million contract to build 'em some custom gear. Under the deal, the company is promising to deliver a "lightweight, see-through, full-color eyewear display prototype" that's a good deal more "wearable" than some of the displays now in use (as seen above). Eventually, the company says the displays will be as small as protective eyewear or "high-fashion sunglasses." Not surprisingly, the company also foresees a few advantageous side-effects to the deal, saying that it won't only accelerate the available of displays for the military, but for consumer, industrial and medical markets as well.
