It depends a great deal on the incremental cost of going from DVD to Blu-ray. If it costs them $20(no idea what actual costs are) to make it play Blu-ray discs, they are going to do it.
The overall mpg of the vehicle is relevant to the consumption per mile, but the relative efficiency of the engine is irrelevant. A car that gets 30 mpg burns 1/30 of a gallon to go 1 mile, a car that gets 20 mpg burns 1/20 of gallon to go 1 mile. It's the per mile consumption that is interesting, not the efficiency that the consumption occurs at.
In practice, most people get 20 mpg (in the US anyway), so they go about 20 miles on the equivalent of 36 kilowatts hours of fuel. You are saying that the power company turns 36 kilowatt hours of fuel into about 18 kilowatt hours of electricity. Fudge that down to 15 kilowatt hours of electricity and fudge the mpg up to 30 and you do indeed end up with 500 watt hours per mile, which would be 1-2 hours on a 250-500 watt system. Fudge up to 20 kWh and leave mpg at 20 and you get 1000 watt hours per mile.
I went from the family Apple IIe to the family 486 running Win3.1, to my first computer, a Pentium II 333 running win98 and then win2k, to this laptop, a core duo 1666 with XP. Power consumption went up with the 486, probably stayed about even with the PII and took a nosedive with the laptop. I had the PII for 8 or 9 years(or used it, it's sitting right over there), the laptop is at 1.5 out of what is hopefully at least 4 years.
It's likely I will replace it with a laptop(not a gamer, so why not...), I don't expect that the power consumption will be worse(the new one will probably have led backlighting and lower power main storage). The trends aren't that bad when you consider that most people are not enormously concerned with high end game performance and buy laptops for the portability (and dual screen support in software is to the point where the screen isn't really a limitation for laptops).
I don't really think I said not to worry about the little things. I said(or rather, implied) that talking up the little things while ignoring the big things is inane.
Moving into a larger house that is further away from work and then going on about how great the energy savings from CFLs are is the kind of thing I am talking about. Figuring out how to live 15 miles closer to work is going to save 5 gallons of gas a week. CFLs conversion won't even touch that(~600kWh/month). Sure, it's good to make savings wherever possible, but it needs to be a mindset, not a checklist.
Part of it is that once you have made the basic efficiency improvements, encouraging other people to make basic improvements is a better use of time than trying to go from 80 watts of lighting to 75 watts of lighting (because they can generally make much bigger savings with much less investment of time and effort).
Well, they have a good infant mortality rate relative to their GDP, but if you look closer, I think you'll find that infant mortality rates don't include stillborn babies, and that Cuba classifies quite a lot more babies as stillborn than the United States(for the simple reason that Cuban hospitals don't have anywhere near the resources that US hospitals have, incubators, drugs, etc).
Waving hands around about efficiency and so forth, that's 1 kilowatt hour of energy per mile driven. So that's 5-20 hours of computer use (assuming between 50 and 200 watts, 500 watts is still 2 hours) per mile driven. Using a more efficient computer is good, but finding a way to not drive 5 miles a day is a considerable amount better.
(If you aren't worried about it, that's fine, but if you are worried about it, for god's sake, do the easy, effective things before you start telling people about the difficult, pretty much a wash things that you are doing.)
The poor interpretation of the numbers is also apparent in the summary. The summary says "20% of GNI for businesses" but doesn't make it clear that it is talking about the pricing for business software relative to GNI (it encourages the interpretation that businesses are spending 20% of their income on Microsoft software).
The phrasing in the summary also suggests a comprehension problem. I don't really think Taco would make the mistake except out of laziness, but I think the submitter made the mistake because of stupid, not malice.
And yet there isn't a whole lot Microsoft can do to stop a distributor in Mexico from shipping the boxes to Cuba. If Microsoft honored the license they would be in violation of the law, but I don't see how the mere presence of the software in Cuba is automagically their responsibility.
If you sold me a loaf of bread and I sold it to Cuba, would you be culpable?
Why would you think that software would be any different? If Microsoft was involved in setting up intermediaries to deliver software to Cuba and it happened at the board level Balmer might get some heat for it, but he can't do a whole lot to stop a distributor in Mexico from shipping stuff to Cuba.
Things like 'adherence to the golden section' sound an awful lot like the composer is substituting a demonstration of how clever he is for the stuff that Beethoven and Mozart called music.
The public school system isn't stooping to anything. The DSO is stooping and using the resulting gift to help the schools. Everybody involved is clearly an asshole.
Abusing your analogy, you are suggesting that even if there were a safe moon rocket, they should build another one because they might learn something and at least they would get to have fun.
$2,000 isn't that ludicrous a price to pay to tie into the grid when you consider that you then don't need nearly as many batteries or have to deal with any sort of choosing new appliances or new wiring.
A lot of people with stuff to sell already have cell phones. There are relatively poor fishermen in India who call in to shore to find out where to go to sell their catch.
Is the radio on the XO powerful enough to actually connect remote locations?
That *are* going from 12/14 volt systems up to 36/42 volt systems. I think there is 12 volt electric steering out there, but it is easier to do at 36, and AC can go electric at 36(the electric losses are better than the belt losses and not always present).
I have an engineering degree(That is, I has enginer degre). I took 20 credit hours of humanities, none of which were sociology or psychology(2 economics classes, just enough to be dangerous, 2 philosophy classes, which is also just enough to be dangerous, and an early American history class that was way more forgettable that the book "1776"). If the school is pushing more than that, it probably isn't a good school.
Much better to make the company who issues credit to an impersonator responsible for the credit they issue rather than the person who matches the mystical, enchanted number (I don't know what else could possibly make a number secure) that was used for identity.

Look in my comment where it says "using a more efficient computer is good".
They probably meant a programmable thermostat.

If you are really worried about it and you drive, drive less.
1 gallon of gasoline = 131 megajoules = ~36 kilowatt hours.
Waving hands around about efficiency and so forth, that's 1 kilowatt hour of energy per mile driven. So that's 5-20 hours of computer use (assuming between 50 and 200 watts, 500 watts is still 2 hours) per mile driven.

They don't have better care. Somewhat ironically, they have more democratic care, but that's about average availability, not level of quality.
The US probably even delivers more care per person on average, it just gets concentrated more.
What does "sound better" end up meaning though?

I'm pretty sure it means "fixed at 400 fps" rather than "just 400 fps".

I was a Philistine once. Then I moved to Toledo.
Or you could just hack it to be plugged into a power strip that has a switch.
Not so nice for systems with a clock, but a genesis, no problem.

No one would offer financial services anymore.
