I think you're confusing the TSA with the FAA.

From what I understand while the rule was originally conceived because of interference with the first generation cell phones with the navigation equipment, this has since been corrected in both the airplane navigation equipment.

The rule is still in place though because the FAA and the airlines want you able to pay attention in case of emergency. You can hear the warnings or commands if issued by the flight crew because you're not using your headphones to drown out all the noise. Or get your headphones caught when you're trying to exit the plane preventing you or someone behind you from exiting the plane.

Besides if you cannot putdown the device for 15 minutes on each end of the flight there is something wrong, but it isn't with the FAA or the airlines.

Yes and no. Only Gamma radiation is electromagnetic in nature. Alpha and Beta radiations are not photons at all, but atomic particles ejected with high energy. An Alpha particle is a helium atom without electrons and a Beta particle is free neutron.

Depending on the radiation source you may get any of the radioactive emission types and all three are dangerous, but to differing degrees depending on volume and location of exposure.

The original press release says US$2.7 billion so its in USD and not Mexican pesos.

Actually,

Revenue - Costs = Profit

This only works though if some one is willing to pay for more for the service that the costs. So far that answer has been no.

[L]eave physical object delivery to the private shipping companies.

Unless you live in a largish city, they won't do it, now or in the future. They hand this off to the USPS since there is no way they can ever do this profitably since there isn't enough volume to justify staffing, warehousing, etc.

Honestly it works both ways. USPS pays FedEx and UPS a small portion of what it gets to ship a letter to have them move the mail in bulk across the US, since it's cheaper to utilize their air and ground freight systems instead of building its own duplicate system. If the USPS wasn't hobbled with things like the pension pre-pay and the inability to control it's prices, everyone would be making profit.

According to the Supreme Court in AT&T Mobility v. Concepcion, the term to ban class actions in a EULA or other non-negotiated agreement is actually valid. As such the term is getting added into every EULA during the re-writing process since the benefits are overwhelming (basically preventing a normal consumer from every suing you for fault since they could never recover enough to make it worth while) and the costs are nothing.

You can be the most profitable and still lose money, if all your competitors are losing more than you are.

Unfortunately, while Samsung breaks down profits by division (their mobile phone division is modestly profitable, but no where near the margins Apple has), they do not break down their profit by individual phones. It's implied that the S3 is driving the profits of the division because of the number of units shipped, but at this point it's all analyst conjecture. For all we know they're losing money on the S3 and making it up on other phones.

Yes.

But for Security! Instead of you know, what ever reason we used them before then got rid of them the first time around.

Nope. It shut down on 30 June 2012

IE6 benefited from some anti-competitive anti-bundling agreements with the OEMs that Microsoft got wrist slapped for by the DOJ.

Because the OEMs couldn't bundle another browser, the main competition, Netscape, basically imploded due to lack of revenue. This left the market without a viable competitor. Giving IE all the space it needed to monopolize the market.

They are a one trick pony, but that pony isn't x86. It's never been their processors or their designs, but their manufacturing capacity. The fixed costs are so high to build a fab, that if anyone seriously tries to challenge them they basically cut them off at the knees in terms of price before their production capacity is even built. And since the marginal costs of each processor is very low, they have a huge margin to do it in.

They'll let AMD and others squeak by for anti-trust reasons, but no one can challenge them on manufacturing costs, not even the ARM producers.

Intel isn't paranoid enough to survive, methinks, and will be left behind.

This is Intel. They are by far and away the most paranoid of all Silicon Valley companies. It's in their DNA. Their unofficial motto is "Only the Paranoid Survive".

This has been inferred for last 4 years or so, but somehow it never seems to come to pass. First it was the newer SanDisk mp3 players going to eat into the iPod margins, then the new Android phones would eat into the iPod margins, then the new Amazon Fires would eat into the iPads.

Somehow through all of the competition their margins just keep getting better.
