Google and other online map-providing companies supplement satellite imagery with aerial photography, and as far as I know, there are no limits on that sort of thing.

The focal distance of the Rift's lenses are set at infinity. In effect, when you're wearing the rift, the focal target is a great distance away.
Having owned both the kindle with the keyboard, and the paperwhite, the keyboard had lots of issues. The keyboard wasted a ton of space despite being virtually never used, and the lighting solutions, while functional, could have looked better, and were not that battery efficient.
I think my ideal kindle would be the Paperwhite, but with physical page turn buttons.
I think your mass figures are off, that's above the maximum takeoff weight of a 747 (442mt), let alone the weight of the empty aircraft itself. Of course, somehow this 747 got into orbit, so the maximum takeoff weight is kind of meaningless.
An empty 747 weighs 178mt, and a submarine reactor weighs about 110mt. It's true that there are micro reactors that can produce about the same output at a fraction of the weight, but let's just say that we also need some radiators for cooling (since there's no active cooling in space) and call it as using up that extra weight. Some weight for the thrusters themselves, and perhaps 300 tons is a feasible weight for an unmanned spacefaring 747. Which is a totally insane phrase to say, I'll admit.
What atmosphere would a 747 in space have to contend with? Of course it's absurd to have put a 747 in space to begin with, but then that was bluefoxlucid's example, not mine.
Luckily, there are existing electric propulsion technologies. They don't provide much thrust, but they're extraordinarily efficient (they require so little "fuel" as to effectively not be using any, with VASIMR producing roughly 10x-20x the fuel efficiency of chemical rockets, and the current VASIMR engine is very inefficient in terms of heat loss and such). The problem is that we've never had any large source of power in space, so while electric propulsion is great for getting your probe around the solar system with a minimum of fuel consumption, or perhaps automated cargo runs to some future colony that isn't time sensitive, they're not going to get you anywhere.
However, if you fit a nuclear reactor inside a 747, strap a bunch of if VASIMR thrusters to it, then that'd actually work. You wouldn't get much thrust, though... the 200 kW VASIMR engine produces only 5N of thrust. If you put a nuclear reactor on the thing similar to what you'd find in a submarine, you'd get 300N of thrust. Compare that to the "Draco" rockets used by a SpaceX dragon as manoeuvring thrusters... they have 400N of thrust.
Except in this case, Oculus and Samsung aren't operating as competitors, they have a partnership for producing VR devices? Samsung is contributing hardware to Oculus, and Oculus is contributing software to Samsung.
Dual screens was never in the plans for any Rift, why would it be a surprise or a disappointment? The consumer version is expected to use at least a 2560x1440 display.
Realize what now? The description said an Exynos for $30, and it isn't.
The Pi is too slow to do things at which it would otherwise be well suited, like for digital signage applications. A cheap little machine that can be stuck on the back of a TV doing nothing but running a fullscreen web browser would be handy.
The description says an Exynos SoC for $30. The description is incorrect. Is it really so insane to have hoped that the information in the description was accurate?
I'm sick of paying $16 for eBooks when the hardcover version sells for $12... I'm with Amazon on this one.
And it's too bad, too. The Raspberry Pi is a really neat little device, but the CPU performance limitations are really tough for a lot of use cases. As I read the description, I was excited at the idea of having an Exynos with modern ARM processors at the $30 pricepoint, but... nope.
I was thinking of a different meaning of the word "stroke".
*woosh*
I'm amused at the mental image of something being destroyed by a "drone stroke".
It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
