From the third ship's perspective in your analogy, each ship travelled half a light year in half a year, in opposite directions. Those ships are one light year apart, therefore their relative speed was 2c, from the perspective of the third ship.
My macbook pro went from about four hours battery life to over six when I put an SSD in. The power saving alone is well worth the $100 it cost. Then there's the speedup on top of that. The irritating wait times for disk access aren't for sequential reads, they're for random reads, and waiting for the disk to spin up.
Dispensing with the FUD and gratuitous slurs: Mac Minis, iMacs and other small form factors don't have problems with maintainability, heat, nor "cooking."
Nobody needs tiny. But it's nice to have. It's easy to put on your desk, install, replace, move, dust. Very, very few people need an i7 blah blah blah. A little fanless ARM machine would do just fine for probably 99% of people, including the corporate types. Most people use the web, e-mail, word processing and maybe a spreadsheet or accounting program. These ran just fine on 386s. They'll run no problem on a modern ARM processor. No, modern machines DON'T need fans and air circulation.
Yes, tablets are lower performance than desktop PCs. That's a GOOD thing. No fans. Much nicer form factor. Trading something almost nobody uses (performance) for things people want (form factor, simplicity, weight, quietness). As I said in my post that you seem not to have bothered to try to understand: "personal computing isn't dying, we've just got the technology now to put it in a form factor that actually matches peoples' needs."
Assuming you (and all the people who modded you up) are programmers, apparently it doesn't require reading comprehension. The guy didn't even mention widgets or dragging and dropping.
I actually thought you'd accidentally replied to the wrong post. If you did, I apologize.
Careful, you just told a bunch of Slashdotters with mod points that they're not as special as they think they are. I see you have a nice shiny troll mod to show for it. Wear it with pride, it means you can think for yourself.
By "properly," you mean "the way I think they should," of course.
Most people simply don't need a conventional PC, and that includes in the vaunted business or (shudder) "enterprise."
From the mailroom clerk up to the CEO, from Grandma to the CEO's kids, most of them would be better served with a small form factor PC. Any of them who are likely to need to take their computing on the road (or to the couch), including the CEO, salesmen, Grandma and the CEO's kids, are probably better off with a tablet, probably with a monitor and keyboard on a desk somewhere.

Thus the pamphlet warning that homeopathy is crap. You could also only approve it for things like the treatment of colds. Homeopaths shouldn't be allowed to make claims about serious diseases anyway.
Despite your opinion and a lot of efforts by many people over centuries, people still insist on believing things that aren't true. Placebos also have a long medical history.
Ha ha ha ha. I was waiting for the first person to suggest this. Google, the world's greatest data aggregation and advertising company, patents using aggregated data to sell people stuff at the maximum price, and you think they're doing it so it can never be used? Yeah right.
First, the delay was due to the time it took for radio signals to travel from the outskirts of the system where the hyperwave buoy was located, to Earth. That type of hyperwave propagation is "near instantaneous."
Second, we're making stuff up, so I can make hyperwave go as fast as I want. I was stealing names from Niven though. On second thought, it might be more interesting to steal from Hogan, and just have tachyon communication where the message gets there before it was sent.
Considering that nobody went faster than a horse can run until the 19th century, and it was believed by some that doing so would kill you, how do you know that moving faster than a horse can run doesn't steal your soul? Certainly, you shouldn't take that chance, no matter how soulful a person might appear after stepping out of a car, plane or train.
So your problem is that it happens too fast? What would be an acceptable delay? A nanosecond? Ten minutes? Twenty? An hour? Day? Week? Clearly a year is okay....
In a hypothetical teleporter every one of the elementary particles in your body is effectively replaced with one that is in precisely the same quantum state as the original, except for position. Since elementary particles with the same quantum numbers are interchangeable, the "new" you is you, more so than the you that took a year, a minute or a microsecond to make the trip.
Yours is a semantic objection, and a nonproductive and ridiculous one at that. If you take a one year round the world trip, the "you" who arrives home won't be the "you" who left either. Essentially all of your atoms will have been swapped for others. Does that mean airplanes, cars and ships aren't transporting anything either?
It's actually precisely the way teleportation works in Star Trek and most other fiction. The teleported version is a copy that it reassembled at the destination. Usually the original is destroyed (which is actually a requirement of real quantum teleportation), except when the writers are stuck for a plot idea and there's a teleporter accident.
If you're going to depend on new physics, why limit yourself to quantum entanglement? Pick something else. Personally, I like hyperwave better. You don't need to exchange particles first. If we'd only put hyperwave on Voyager, we could talk to it instantly! Of course, we could have just built it with a hyperspace shunt and not had to wait 30 years for it to clear the solar system in the first place....
Any condition the patient believes is treatable by homeopathy, is. It doesn't work as well as approved drugs, but for minor conditions where there isn't really a treatment (like a common cold), it's better than nothing and saves prescribing actual medicine as a placebo.
Homeopathy does work, in people who believe in it. Tap water is cheap. If someone believes in homeopathy enough to demand it, maybe a vial of tap water SHOULD be covered. It's probably cheaper than many other, usually ineffective treatments for untreatable or minor ailments. Walk into a doctors office with the sniffles and a bad attitude and instead of leaving with useless antibiotics you're given a bottle of water (I mean, super diluted phlegm) and a nice pamphlet warning you that homeopathy is bull.
If there's no cell service you're probably not going to magically find someone who's got open wifi either. And at least the cell phone in each truck solution might work when there is cell coverage, as opposed to the wifi mesh networking, which is likely to be useful never.
And there was more than a few times during the summer and we were fighting multihundred acre brush fires that I wish I knew exactly where each truck was, how much fuel and water they had onboard, and be able to set a waypoint for them to drive to for their next task.
If you can't see the other trucks, wifi mesh networking probably isn't going to do you much good. You'd be better off issuing each truck a firefighter who owns a smartphone and has one of the location sharing apps turned on.
Unfortunately I think the contrary posters are right - this fire department would be much better off getting some used radio equipment and figuring out some procedures rather than investing the money and especially time to fiddle with finicky wifi mesh networking that will rarely work anyway.
I think the real question is, is a fancy ad hoc wifi network that will eat up a lot of time to set up and maintain, and a fair amount of money to equip, worthwhile, or would it be better to just put a cell with a data plan and tethering or a mobile hotspot in each truck?
Really, how likely is it that you're going to have a bunch of firetrucks out where there's no cell service but strung out in such a way that one of them manages to slurp someone's unsecured wifi and the others can't see it, but they're all close enough to share?
on an android tablet you can(cumbersomely) develop a real android app.
You've got it right there. Developing apps on a tablet is a parlour trick that doesn't really matter. You can do it on Android or a jailbroken iOS device, but nobody cares because it's FAR easier to do it on a bigger computer.
It was very irritating when Apple forbade interpreters so you couldn't do simple things, but not supporting building full apps isn't really a loss.

Two seconds. For both. That's the point.
From the third ship's perspective in your analogy, each ship travelled half a light year in half a year, in opposite directions. Those ships are one light year apart, therefore their relative speed was 2c, from the perspective of the third ship.
That doesn't mean you can go back in time to to the SAME place in space.
My macbook pro went from about four hours battery life to over six when I put an SSD in. The power saving alone is well worth the $100 it cost. Then there's the speedup on top of that. The irritating wait times for disk access aren't for sequential reads, they're for random reads, and waiting for the disk to spin up.
And it sure is less than $1 a gig.
The submitter isn't the best writer in the world. The editors are probably close to the worst.

Because I criticized Google. Posting something critical of Google on Slashdot IS flamebait. It shouldn't be, but it is.
Ha ha ha ha. I was waiting for the first person to suggest this. Google, the world's greatest data aggregation and advertising company, patents using aggregated data to sell people stuff at the maximum price, and you think they're doing it so it can never be used? Yeah right.
No, you can't. Quantum teleportation destroys the original as part of the process and allows the creation of only one "copy" at the destination.
