People don't buy a phone to get Google Now or Siri, it's a convenient extra. People buy the Echo almost certainly for the voice control as that is it's main selling point. Numbers aside, 3x growth at that scale appears to indicate ongoing and growing demand.
The scanning part isn't the problem, it's everything else that is: The triplicate passport checks, the questions, the confused passengers, having to take off your belt, coats (and sometimes shoes), laptops, loading onto the belt... and the reverse after scanning - And that's just the inefficiency in the security line process.
Tesla took a huge risk by taking a completely new technology (battery-powered cars) and applying it in a completely new and untested way (performance car). They went into it knowing that they'd be taking a loss for the medium term.
If Tesla are already at taking only a $4k loss / 10% loss, they're doing extremely well:
- The "Supercharger" units that are being aggressively installed across many countries will be accounted for within this unit cost... It won't be long until they reach diminshing returns on their deployment, and the impact of this will tail off.
- They added a number of new product lines, all sinking huge money into R&D. They're close to establishing a range of products so the impact of this will tail off shortly.
Musk could easily choose to add $4k to the sale cost of each cars with minimal impact and result in a 0-dollar P/L, but increasing production count ensures far better long-term return by economies of scale improvements, as well as learning opportunities when scaling aggressively.
"There is, however, one large problem: What if a person mistypes a password? In that scenario, a fake vault is generated, and a user is locked out of his or her accounts."
This is the weak point - It forces the user, or the system, to generate an additional artifact to inform the user (but hopefully not the attacker) that the password safe is correctly unlocked.
"One possible fix is to create a hash of the master password that is linked to an image that is shown when the password is entered. The authorized user should recognize when the wrong image is displayed, but an attacker would not."
I'd expect this one image to be shown only when the master password is entered. i.e. it is an unique indicator. Fake images will need to be generated for all other passwords, and if there are duplicates then they can be eliminated as false-positives. Strategies like this will always be the weak point. It's commendable that they're attempting to fix the problem, lets just hope the additional complexity doesn't weaken the system overall.
That's fine, just be aware that Indispensable == Unpromotable.

Amazon isn't 'losing money' - Just take a look at it's top-line growth vs capital expenditure.
Amazon is re-invest revenue instead of distributing back to stakeholders, or keeping cash in the bank. Cash in the bank is seen as waste. Instead, cash re-invested is being leveraged to create accelerated future growth.

I hope the malware writers (or the US gov't) have agreed their license fees with the respective record companies, otherwise they'll find themselves in a world of pain!
And we do have an idea of what's actually going on. Here's a detailed example of the recent Facebook IPO problems: http://www.nanex.net/aqck/3099.html.
