There are many fantastic technologies out there. Some are in early phases, some are suppressed, some are just not feasible commercially.
Conductive cloth like material.
Imagine a LCD screen that can be folded like a cloth. saw his on the discovery channel, wish I could find a link :(
Permanent Batteries
By using the Casamir Effect(http://en.wikipedia.org/wiki/Casimir_effect) a permanent battery(length of material) can be made. Though what battery company would want to make a battery lasting years is my guess. Theres also perendev motors that can supply infinite electricity without pollution. Again not profitable enough for corps.
Augmented reality
All the tech is exists to have everyday Star Trek like augment reality.
Glasses like digital display that doesn't obscure sight. Check.

Image processing unit(http://en.wikipedia.org/wiki/Mobile_phone) that everyone could use.
Worlds tracking device for city street layout(GPS, what else)
Theres so much insanely cool tech out there that the consumer will never see as "future tech" until it's 50 years too old.
Squilliam: On Vgcharts its a commonly accepted practice to twist the bounds of plausibility in order to support your argument or agenda so I think its pretty cool that this gives me the precedent to say whatever I damn well please.
