Some of the things you originally mentioned like wages, taxes and transportation costs won't be significantly different between LEDs and incandescents. For other things you mentioned the prices will go down as they are mass produced and further efficiencies are found. Of course this will take time and LEDs will probably never be as cheap as incandescents, but at some point in the future they'll probably be at a price where there is no sticker shock.

In this context you only need to get the price down to be close to that of incandescent bulbs.

As production of LED bulbs increase their costs will go down.

Don't need to judge by the cover, you can read an excerpt here.

I recommend the book highly.

Thingm has a similar series of products called blink(1). It runs for about $30, but it is not widely available now. They recently finished .

Adafruit is now accepting bitcoin. I think they're crazy.

You're correct. The apostrophe isn't used in English for a glottal stop, but it is used when other languages are transliterated into English, like "T'Pol".

The apostrophe is often used to represent a glottal stop like in the English "don't". Perhaps whatever language the "Qa'an" version comes from uses a glottal stop. Given the large number of languages and the variety of ways of representing those languages in Roman characters you end up with a great number of representations.

Most of their code is on github, https://github.com/adafruit . Did you not find it there?

Apple and Microsoft are at a patent truce. They co-own the patent holding company RockStar.

You're both right and wrong.

Right about Papua, wrong about Tasmania. Tasmania is part of Australia. (Or perhaps this is some Australian joke?)

If they don't read the slashdot stories, then they don't read the posts either. We're doomed.
