No one will use it because:

A. The people posting the pictures don't care (at least at the time they are posting them)
B. Facebook doesn't want it to work and they have the power to stop it by not allowing encrypted pictures. (If they wanted this feature, they would just provide it themselves by removing the content on a given date.)
C. Even if posters cared enough to use this system, no one would be able to see their pictures because

and posters want people to see their pictures (which is why they are posting them online)
D. It is too easy to circumvent

I believe you mean "damn pedants". Pedantic is an adjective.

Just sayin...

When was the last time you saw the original? The similarities extend much further then the colors and the setting: the original story was also hackneyed and the original acting quite flat. At least this one has Daft Punk.

It's about the size of your thumb. It contains storage, processing power, wifi, cell voice/data connectivity, and a battery, but no display. It can plug into various, standardized input/output units including touch screens (ranging from pocket-sized to large tablet), TVs, PC stations (which are just dumb monitor/keyboard/speaker modules), cameras, video game controllers, your car, simple headphones, eInk displays, etc. You can plug and unplug it from these things on-the-fly. Wherever you plug it in, all your app(lications) work in whatever capacity is appropriate to the size and functionality of the display. On your pocket display, they act like smart-phone apps, at your home desk-station, they act like PC applications. You can upgrade your peripherals independently from your core.

I see no technological barrier to building this family of devices today. Is anyone building it?

I used to really like the word "ergo". Now it just makes me think of the Architect from those fake Matrix sequels.

His definition would not classify Rambo as science fiction. He clearly emphasizes that in SF there is only one impossible thing (which seems a little arbitrary) and that the story focuses on what would happen if that thing were possible. His definition might classify Rambo as fantasy, but it isn't clear.

Apparently that isn't quite true. The link he provided implies that people can check on behalf of their friends. See items 9 and 10.

It says bully pulpit. Which is something else entirely.

You've missed his point rather badly. He isn't saying he wants background processes that never sleep. He's saying he wants process that are allowed to do some work, some of the time, when they aren't the actual task in front of the user on the screen. Sure, they might sleep most of the time, but they might, say, wake up for 10 milliseconds out of every 300 milliseconds to process a data stream, decide not to bother the user, and then go back to sleep.

That said, I don't think you deserved the troll mod. Maybe, "+1 Incorrect Point About A Interesting Topic".

Why would you prefer a model where you pay $60 per year and you have a decide on a click-by-click basis if you want to spend the money over a model where you pay $50 per year and can read whatever you want on a whim?

On days when I visit the NYT I probably click on twenty articles. Most of them I "read" for about 5 seconds. A few merit more attention and a I read them more completely. I like this freedom to skim. A pay-per-click system would make that cost prohibitive.

I think the future model is going to be a small number of iTunes-style markets for media content that are (somewhat) independent from the media providers. You go to one place to spend your money and manage your purchases (eBooks, mp3s) and your subscriptions (NYT, Pandora, Hulu) and you get one account that lets you access multiple sources from your eReader, your browser, your phone, etc. This system has already begun and will mature quite a bit at the end of this month when Apple announces their iPad. Within a few years several such markets will spring up and then consolidate down to 3-5 major "networks". This model will be both better and worse for consumers, but publishers will get paid so it will stick around.
