Dell has much lower overhead than Apple. Apple has to spend a great deal of money on engineering and software development. That requires higher profit margins.
Even so, the price difference between comparably equipped Intel and Apple systems is not that big.
There are many organizations that do not have a budget or process for replacing obsolete/outdated equipment. Like rain in the desert, money for new equipment comes in infrequent deluges. When money is available, you buy the top-of-the-line computer. You may be using it for the next ten years.
Odd things can have psychological associations. I've noticed something similar with typefaces. Your brain builds associations between typefaces and emotions based on the way typefaces are commonly used.
I've talked to a few cinematographers and they all believe 24 fps is an important component of the "film look", along with grain and other artifacts of film technology. There are effects houses that say they can make digital video look like film.
I had a VW Jetta that blew its engine when it was a few weeks old. One of the pistons disintegrated due to a defect in manufacturing. The dealer sent the parts back to the manufacturer for failure analysis. It's rare, but such things do happen.
MTBF figures are usually associated with a design lifetime. That hard drive may have a 300,000 hour MTBF based on a 100% duty cycle and a 5 year design lifetime. That tells you the expected failure rate for the first 5 years of operation. After that point, the failure rate may increase rapidly.
Network interface cards are already bumping into the bandwidth limits of PCI. Gigabit Ethernet will soon be cheap enough for mass deployment. 10 gigabit Ethernet is on the horizon.
Digital has the advantage of supporting error-correcting codes and interleaving. Suppose you want to transmit four 512 byte blocks of audio data. Rather than sending the bytes in normal order, you can interleave the blocks, sending byte-1/block-1, byte-1/block-2, byte-1/block3, byte-1/block-4, byte-2/block-1, byte-2/block-2, byte-2/block-3, byte-2/block-4, etc. This limits the damage a fade or noise burst causes to any single block. Rather than losing a whole block. the damage is dispersed in time, resulting in less severe errors that can be corrected by the error-correcting code.
They already have such a device. I don't know its official name but it's a water gun designed to disrupt bombs without setting them off. It reduces the bomb to small pieces.
The current depends on the voltage and the skin's resistance. If the skin is intact, 50V is unlikely to cause a problem. 100V will definitely "bite" you. AC is worse than DC, and higher voltages can arc through the skin, greatly reducing the resistance.
42V is below the threshold (50V) where the rules change concerning electrical safety. It is still considered a low voltage circuit, with minimal risk of electrical shock and injury.
Many manufacturers have co-op advertising programs, where they subsidize the advertising of their products by retailers. If you are a retailer and you want to participate in the program, you have to follow the manufacturer's rules. For example, Intel wants their logo displayed in the ad plus you have to play their jingle if it's on television. They may prohibit the retailer from advertising the price if it's below a minimum price set by the manufacturer. The manufacturer is not prohibiting the retailer from selling at a lower price, they just can't use manufacturer subsidized advertising to advertise that price.
How much hardware will have to be replaced in the networks owned and operated by the telcos and cable companies? Most of my computers are IPV6 capable but my ISP may try to postpone supporting IPV6 if it requires massive network upgrades.
If your organization had made a significant contribution to the early development and deployment of IPV4, they might have a class A network too. If you don't like the address allocations or the structure of the domain name system, too bad. The people who provided the funding, and did the development and deployment, set the rules.
The U.S. government does try to use metric units when it is reasonable to do so.
Excerpt from NASA Policy Directive 8010.2C:
b. Require consideration of the metric system of measurement for
all new programs and projects and New Capability Construction of
Facilities (COF) Projects, and use the metric system of measurement in
related NASA procurements, grants, and business activities, unless such
use can be demonstrated to be impractical or likely to cause significant
inefficiencies or loss of markets to U.S. firms.
Other government agencies have similar policies, based on Executive Order 12770, Metric Use in Federal Government
Programs, July 25, 1991.
It seems rational to me. You are punishing the other player for antisocial behavior, by accepting a short-term loss to encourage better behavior in the long run.

I believe Eddie Murphy referred to percentages of net profit as "monkey points". Major players get a percentage of the gross.

The original HPFS (OS/2 1.2) was written for the 80286 by Gordon Letwin of Microsoft.

You won't find this at Walmart.

The Comet? I prefer planes that don't fall out of the sky.

The higher voltage electrical system is needed to power vehicle mounted radios and other military electronics equipment.
The telephone company uses a negative supply voltage (positive ground) to reduce problems with electrical corrosion. See http://engr.smu.edu/~levine/ee8302/positiveground. pdf.

Most of the spam that I receive comes from South Korea, Russia and China, not the United States.
