I haven't noticed it since HSDPA/WCDMA/LTE have taken over.

You are right about people. You could have 99 people on a plane that can close a laptop or hold a kindle and proceed to an exit. It'll be guy #100 that fiddles with putting the laptop in a sleeve and getting his bag out from under the seat to put it away, and luck will have it that he is sitting in an exit row, blocking people from getting off of the plane. Perhaps people who fail the certification can be seated furthest from the exits so they do not inconvenience the rest of us.

Cell phones though, as I posted above, is tied to an FCC rule. The FAA could completely overturn the PED ban, but you still couldn't use a phone from wheels up until wheels down until the FCC decides airborne cell phone use does not interfere with the ground network.

The real reason for the ban on portable electronic devices (the cell phone ban dates back to an FCC reg on the adverse effect of having an old-school cell phone at altitude where it could see many towers) is not to protect against interference, it is to protect lives in case of evacuation.

Are you sure about that? I mean honestly knowledgeably sure?

Here are relevant regulations governing use of cell phones and portable electronic devices:

14 CFR 91.21 Portable electronic devices.
(a) Except as provided in paragraph (b) of this section, no person may operate, nor may any operator or pilot in command of an aircraft allow the operation of, any portable electronic device on any of the following U.S.-registered civil aircraft:
(1) Aircraft operated by a holder of an air carrier operating certificate or an operating certificate; or
(2) Any other aircraft while it is operated under IFR.
(b) Paragraph (a) of this section does not apply to—
(1) Portable voice recorders;
(2) Hearing aids;
(3) Heart pacemakers;
(4) Electric shavers; or
(5) Any other portable electronic device that the operator of the aircraft has determined will not cause interference with the navigation or communication system of the aircraft on which it is to be used.
(c) In the case of an aircraft operated by a holder of an air carrier operating certificate or an operating certificate, the determination required by paragraph (b)(5) of this section shall be made by that operator of the aircraft on which the particular device is to be used. In the case of other aircraft, the determination may be made by the pilot in command or other operator of the aircraft.

47 CFR 22.925 Prohibition on airborne operation of cellular telephones.
Cellular telephones installed in or carried aboard airplanes, balloons or any other type of aircraft must not be operated while such aircraft are airborne (not touching the ground). When any aircraft leaves the ground, all cellular telephones on board that aircraft must be turned off. The following notice must be posted on or near each cellular telephone installed in any aircraft:
“The use of cellular telephones while this aircraft is airborne is prohibited by FCC rules, and the violation of this rule could result in suspension of service and/or a fine. The use of cellular telephones while this aircraft is on the ground is subject to FAA regulations.”

The FAA has a blanket ban on PEDs and the FCC further restricts cell phone use while airborne. The FCC reg dates back to analog phones and interference when the phone could talk to many towers at the same time, and continues to this day for the same reason, though it has not been shown to be a factor in modern networks. The FCC has a few rules planes have to follow. Every plane you ride on has a FCC radio station license on board, and pilots that may communicate with foreign ATC carry restricted radiotelephone operator (RR) permits from the FCC.

I dont really care about the cell phone ban, and people that do cite the reason as everyone talking on phones. That may be a factor on and near the ground, but at cruise good luck getting a signal (you are at least 7 miles from a tower) and phones these days will drain their batteries looking for a tower and you'll have a near-dead phone by the time you are low enough to actually make a call. You'll also notice that the flight attendant reminds you that you can turn on your phone and make calls as soon as the wheels touch the ground upon landing. The FCC reg on this is not likely to change.

The blanket ban on PEDs may get relaxed, and I am in favor of that. However, I think we'll still see a ban from the time the aircraft closes its doors until it is airborne, and another one sometime before landing until wheels touch down. The goal there is to have things put away during takeoff and landing. The problem is if you let them use things during taxi it is not reasonable to expect them to follow the rules and put them away before takeoff.

The reasoning being evacuation is supported by the other requirements that baggage be stowed above you or completely under your seat during takeoff/landing, that seats are forward and tray tables stowed. This is to provide you with clear walkways to get in/out of rows, navigate the aisles and get to an exit ASAP. Anything that slows someone down is also slowing down everyone behind them. Count the doors next time you are on a plane, there really are not that many.

And lest you think evacuation is still not important, realize that is the primary reason you have a flight attendant. You will have at least 1 for every 50 people on board and they are there to get you out of a plane alive if an emergency occurs. Instructions such as how to brace, how to operate doors and the helpful reminder to leave your bags behind and get off the burning airplane.

If the ban is not relaxed or overturned, look for this to be the reason cited. It is supported by current practices, regulations, training and analysis of accidents.

The biggest threat there are the lap children. Children under 2 years old (or that can reasonably be passed off as that young) are not required to have a seat and can be held by their parents. I would much prefer a requirement that a seat be purchased and (FAA approved...) car seat used. In an event that would send an ipad flying, a kid flying around is a much bigger threat to itself and those around it.

As someone who works in front of the door that says "Authorized Personnel Only" on airplanes, let me throw my 2 cents in.

The only interference I've personally experienced is that infamous noise TDMA and GSM phones make when transmitting data. I could hear the interference anytime myself, my copilot, the flight attendant or anyone in the first 3 rows of the airplane left a phone on and I had the crew audio selected on my audio panel. No effect on the com or nav radios.

The real reason for the ban on portable electronic devices (the cell phone ban dates back to an FCC reg on the adverse effect of having an old-school cell phone at altitude where it could see many towers) is not to protect against interference, it is to protect lives in case of evacuation. If a plane is going to have a survivable accident it is very likely this will occur as a botched takeoff or botched landing, and in these cases you have on the order of a hundred of seconds to get out of the plane before you cook in the fire or succumb to the smoke. Personally I think that people can close a laptop and get up and out of a plane, but past accidents suggest that people will instead close that laptop, attempt to retrieve its case/bag, put it away and perhaps get other bags out of the overhead before evacuating a burning airplane (see the air france overrun in canada a few years back). This is more of a problem with peoples mindset when it comes to protecting property when faced with certain loss, but I think that needs to be addressed before we lift the ban on portable electronics below 10k' .

They wont learn from this lesson, as this is not the first time they've learned this lesson.

A number of their leaked (shame on you) and official (shame on them) updates to android had an flash update that would hard-brick phones. Granted the phones had bad EMMC chips and the update code triggered this bug, but Samsung was told of the bug, told how to avoid it, and even given a community patch. A year later, they have not fixed it and official updates can still brick certain phones.

Par for the course.

He didn't steal anyones work, at best he deprived publishers of profit, which is debatable since not many people who don't already have free access to journals actually want to read those articles.

The journal publishing industry is a huge racket. Editors, assistant editors, peer reviewers, etc are all unpaid volunteer positions. Authors are unpaid and in many cases have to pay money to submit an article (some flat fee, some per page, some extra for color). The guys who get paid are the guys who take your LaTeX submission document and change the style file to the 'journal format' style from the 'journal draft' style and put in the page numbers, doi info, etc. That guy and the executives who run the publishing house. In return for essentially 95% volunteer work to get an article to print they charge exorbitant fees to libraries and universities to get the journals (and some like Elsevier wont even offer you a subscription to the 1 journal you want unless you buy the package that includes 19 others that you don't want).

On top of that, the vast majority of published research out there is paid for by public funds, that you as a taxpayer are helping pay for. If the public pays for it, the public should have access to it. You shouldnt have to pay for the research and then pay to see the results. Sure, there is a real cost associated with printing and distributing publications and with storage and bandwidth for articles available online. The price charges is not inline with those costs though.

Get Play On Linux http://www.playonlinux.com/en/, (your distro might distribute it). It comes with user contributed install scripts for a variety of games (from CD/DVDs, GoG, Steam, etc), which will download the version of wine with the best compatibility / least regressions for a particular title, install needed runtimes, do all the winetricks magic needed and install the games. I've installed a few old GoG games and some newer ones. I'm playing Skyrim through PoL now and it runs (with DLC, high rest textures, and a handful of mods) just fine. Give it a shot, even if you dont have a GPU that will run the highest end games, you can get most of the classics through GoG and install/play them with PoL.
