Yes, they can automatically be unlocked in an emergency.

They have conductors so people won't get stuck in the doors and dragged to their deaths.

They could make the doors automatic, and re-open when someone or one of their body parts is in the way of a door closing, which they do now, but without the conductor there to yell at people to get the hell in or out of the car, the trains would never, ever leave the station. There will always be that one last person trying to get in.

MSFT stock went from 56.125 on 1/14/00 (the day Ballmer took charge) to 49.125 on 1/28/00, and has not broken the 40s since then.

AAPL was at 381.82 the week (9/30/11) before Jobs' death ( on 10/5/11) and went as low as 369.80 two days after his death, before jumping back up to 422.00 by 10/14/11. Aside from the 11/25/11 363.57 price, it has remained above the price it was at his death since then.

$2.80 of the $27.95. Even if you completely remove it, you're still talking about a $22.32 ebook. And if you're going through a distributor, you aren't completely removing it - they still take a cut.

From http://journal.bookfinder.com/2009/03/breakdown-of-book-costs.html (Slightly old)...
Based on a list price of $27.95
- $3.55 - Pre-preduction - This amount covers editors, graphic designers, and the like
- $2.83 - Printing - Ink, glue, paper, etc
- $2.00 - Marketing - Book tour, NYT Book Review ad, printing and shipping galleys to journalists
- $2.80 - Wholesaler - The take of the middlemen who handle distribution for publishers
- $4.19 - Author Royalties - A bestseller like Grisham will net about 15% in royalties, lesser known authors get less. Subtract the author's agent fees and self-employment taxes from that, too.
- $12.58 - profit for the retailer.

In the case of an ebook, you're removing the $2.83 in printing.

You might be removing some of the wholesaling cost, but you might be using Ingram to do your wholesaling if you're a big company. If you're self-publishing, you might be using something like BookBaby or Smashwords. Yes, you can go to KDP and register your own book yourself, but if you're selling in multiple places or selling multiple books, you're going to use a middle-man to handle cataloging, recordkeeping, and listing things in multiple places. If it's more than $2.80 in headaches, you use a distributor.

Marketing, pre-production, royalties all don't change. (Or they get squeezed, and you get exactly what's going on right now, which is authors complaining "they don't pay us or market us or do a good job editing us like the good old days.")

As for that $12.58 of supposed profit, here's the interesting thing - Amazon doesn't sell books at list price. John Grisham's new book, The Racketeer, is an example. List price: $28.95. Yours for only $19.81 in paper.

I'm not saying that ebook prices should be equal to the price of a printed book, but removing the printing doesn't suddenly make a book cost a dollar or even five dollars.

I can't see how the manufacturer is making any money off of the bugs I ran into

They make money by making new phones. Period. If you're holding the phone in your hand, the only way they can make more money from you is to get you to buy another phone.

Yes, I know there are other ways through services, selling apps, customer loyalty, blah blah blah. But the real way is to sell you another phone.

I worked at Samsung. They gave out insanely large bonuses to workers in Korea on phone teams every time a phone shipped. They did not give out bonuses when you did a carrier update. Number of phones shipped is a huge metric, and one they wanted to always raise. Selling the most phones in X region for Y period is a big deal. Fixing bugs in a phone that already shipped isn't.

To add to this problem, workers are paid overtime for hours above a given amount in Korea; they don't have the same concept as the US of a salaried worker that makes a set wage if they work banker's hours or are in startup mode. And when told they need to ship a phone in a year with a team of a hundred, they take great pride in saying they can do it in in 9 months with 50 people. But then everyone works 80 hours a week, and racks up huge amounts of overtime, plus gets that big bonus. And the extra hours and added stress are why you'll find so many bone-headed mistakes in their phones.

It is if your software can only address 640K. You don't add 8 gigs of RAM to your 8088 PC.

If you dropped a wrench on a PDP machine, you're probably going to need to buy a new wrench.
