To add to Ogee's great diagram...
Let's remember, whatever can be done with Silicon, POET can to X fold in GA. So it is great that Intel is making the next gen silicon ATOM processor that provides 1 day battery life at 4.5 watts etc. But if POET came out with a much faster processor that provides 5 days battery life without the need to have multiple chips (lowering manu costs)...it would be even better and still incredibilby attractive to INTEL, Apple etc.
There will always be a market for lower power, faster, cheaper -- POET with GA has the technology and physics behind it to provide this. Virtual reality gaming, always on camera with scene detection, projection phones etc.etc. the technology uses case will continue to push the need for better, faster, lower power and less expensive.
Bill Gates made the mistake thinking we would never need more memory than 640K Memory ina computer-paraphrasing a quote from the 80's. There will ALWAYS be a need for more!!
Hate to quote a movie but Minority Report can give an example of some the tech idea that may come in the future.
