Direct emission green diodes, you know what "blu ray" is? better resolution of wavelengths especially in the blue and violet ranges, well, direct emission green conquers a plague that has hampered green diodes for decades, coherence length, what does this mean?
For the first time we can compact and make smaller projectors, pico projectors they are called, you will have a cell phone someday that will project a movie theater quality projection on a blank wall, the wall plug efficiency, you know, that nasty little habit of apps to drain your cell phone battery? well, that too, will be a thing of the past.
MIT just developed photovoltaic paper, yeah, that's right, you'll be able to put a sheet of photovoltaic imbedded paper on your dashboard, use it to charge your cell phone battery and then chuck it, it will be as cheap as toilet tissue in a very short period of time.
We are on the verge of another leap in technology; I hope all the young engineers I see working on this stuff now, pulling "all nighters" and working like the dickens to pull it off, actually get to enjoy the fruits of their labors.
This is why I am a geek and I love geeks bearing gifts!
