Now if LEDs could only fix their horrible CRI problem and scale to higher output without costing a fortune. lumens/w isn't the only thing that matters.
"...and it's virtually indistinguishable from the incandescents I have"
Indistiguishable using what, your eye? The eye is a notoriously poor distinguisher or color. I promise you that a spectrometer can certainly disinguish.
Why does this matter? Because reflected color does not get rendered properly by light sources with poor spectral content and lack of full spectrum may contribute to depression.
There is nothing less efficient than resistance heating. Furnaces and heat pumps as vast improvements. Just because you can't afford central heat doesn't mean that heating your spaces with light bulbs is "efficient".
Just because the best CFL has a good CRI doesn't mean that CFLs in general have good CRI.
Places you need full spectrum: (1) the bathroom, (2) artwork, (3) kitchen, (4) anywhere where you care about how your colors are perceived. CFLs are generally not dimmable either. By the time you eliminate all the places where you care about light quality CFLs don't have all that many applications. For me it's a small percentage of the home.
"Color Rendition Index (CRI) is a measure of the color quality of a light source. It indicates how accurately colors appear illuminated under a particular light source with respect to a reference source and is measured on a scale from 0 to 100. A high CRI (close to 100) indicates colors can be seen as expected under natural sunlight. While most incandescent lights have a CRI above 95, CFLs have a CRI in the range of 80 to 90 which is considered to render colors adequately. A light source with a CRI below 80 does not allow good color discrimination."
Fact is, though, that many CFLs have CRIs lower than 80 (flourescents are frequently in the 70s) and only special bulbs have high CRIs. It's not the CCT that simpletons like to quote that makes the difference. Flourescents are useless for critical applications because they have poor CRI.
BTW, incandescents inherently have high CRI because they are black body radiators. Photography demands high CRI and the usual standard is at least 95. CFL need not apply.
What's that, a gasoline engine that's louder? Diesels can be quiet but saying they put out "far less sound" is an absurd generalization.
"...and are cleaner burning and less vibration intensive as well."
Now that's bullshit. Diesel engines are not cleaner burning that gas though they can be clean (depends on your definition of clean). They are certainly not "less vibration intensive". Diesels operate under constant detonation whereas gasoline engines specifically avoid detonation. Diesels, by definition, are "more vibration intensive".
"...there are way too many design variables to simply look at noise as an engine constraint."
While that is true, you've proven that you don't understand those variables sufficiently to comment.
You are completely ignorant. Color temps are increasingly of little concern, other than that they match, due to digital. CRI is everything and flourescents have notoriously poor CRI. Incandescent does not pose sepcial white balance problems with digital though balancing light sources is always an issue. You want to talk about balancing light sources, try combining strobe with flourescent.
Why bother with a high efficiency bulb where it's on only a few seconds at a time? The original poster said that the light was almost never used so how much energy savings is to be had?
"The iPhone may be expensive for a "phone" -- but as a pocket computer, it's a pretty cool device."
By any measure, the iPhone is not a pocket computer. It is not programmable by the end user or any 3rd party. Every existing smartphone is more a pocket computer than the iPhone will be and many of those sell for considerably less already.
There's no such thing as a Ferrari 355 "in almost new shape". 15K miles is considered high milage for any Ferrari and the newest 355 would be nearly 10 years old by now. A new Ferrari 430 would be around $200K and some Ferraris do, in fact, cost a million.
"I'm the exact opposite. I -hate- those tiny key keyboards that feel like you're going to split your fingernails on trying to type on them. They're mostly worthless since they take up most of the phone (which would be large even without them). I'll pass on that."
You've obviously never used one, or apparently even looked at one if you think they take up most of the phone, but if you think the iPhone will be easier to use than one of those then you're crazy. The soft keys are the same size or smaller, regardless of what Apple is claiming, and there is no tactile feedback nor any option to use a pen or stylus. The width of the iPhone prevents the buttons from being bigger than the little keys on a conventional PDA phone. As someone who's owned and used both kinds, there is no comparison between the usability of soft keyboards and the real thing, and Apple hasn't done anything to change that despite what they claim.
There ARE limits on what can be done legally. The problem is that dipshits, like ShaneThePain, believe that the ends justify the means in these cases. There is, after all, a TV show entirely based on illegal vigilante entrapment. Sure, the people they catch are mostly likely scuzballs but the organization that performs the entrapment should be prosecuted and the police that play along should as well. Committing crimes is not justified simply because you don't like the victims' (potential) behavior. I find the the producers of the show more reprehensible than the people they expose.
I doubt that communist governments will be good citizens of the GNU community. To the extent that they may make meaningful contributions to OSS code, there's no reason to believe that they'll feel compelled to abide by the terms of the license either internally or externally. Furthermore, it's not the image of the community so much as the image of the person who knowlingly makes positive contributions to the infrastructure of states that are enemies of his own. Frankly, I don't understand why he would be motivated to evangelize OSS software in such countries though it's his choice (assuming what he does respects US law). I'm not sure why anyone considers it positive that Cuba uses OSS software at all. What will that mean to the strength of the OSS community?
There is, of course, the simpler explanation that GNU-licensed software *is* analogous to communism. Saying that evokes outrage because of the emotional reaction to the word "communism" but that doesn't make it any less true. There's no need to suspect astroturfing when there's every reason to expect that a thinking man would naturally conclude such a thing.
There is an age of accountability. Charles Manson had reached it. Parents have reached it. 13 year olds have not. It is expected that parents take responsibility for good parenting and their failure to do so is not their parent's fault. It's really not a hard concept to grasp.

'o illuminating artwork where you need zero UV coming out"
Never illuminate artwork with lighting that offers less than 95 CRI.
LED lighting has horrible CRI.
"In fact there already exist several companies producing fluorescents with very high (95+) CRI in common sizes."
Some references please. I'd like to know where I can buy these since you are claiming that several companies offer them.

"In part I guess it's because it's a cooler colour, which I prefer because I won't get as hot myself."
Is that a joke?
Wood is a far better heat insulator than concrete. CMU construction does not, by itself, lead to a well insulated structure.
I'm sure houses like yours are everywhere.
"And there are a lot of places like mine, many, even, in the city."
Have some extra commas to use up?

You don't have to delete EDGE to add 3G. Is a 3G+EDGE+WiFi way less useful than an EDGE+WiFi device? Didn't think so.

Communism fails to tap into a great human motivator--greed. Capitalism uses greed to drive economic growth.
There's nothing about communism that says that people have to work together either.
Nice try, but no cigar.
