LCD panels are produced in large sheets and cut to size, so it's the pixel density that matters, not the resolution. The pixel density of 1080p computer monitors is generally very different from that of a 1080p television, since the television is normally much larger.
If memory serves, superchargers can give do a 50% charge (150 miles) in 20 minutes; the plan is for people who need it faster to do a battery swap (would would take much less than your six minute pitstop) at a cost based on local gas prices.
You're not going to be emptying a model S battery during anything but long-distance driving, though, and you're going to start each day with a full charge, so your scenario of a 6-minute carry-out isn't going to be realistic unless you intend to consume that meal while driving the car.
The hindenburg had about 202,000 cubic metres of hydrogen stored at atmospheric pressure. Wolfram Alpha tells me that would be 1.66 metric tons.
Some googling turned up Toyota SUVs with an 800 kilometre range have a hydrogen storage capacity of 156 litres at 700 bar. Wolfram Alpha tells me that means the vehicle holds 6.1 kilos of hydrogen, or 0.0061 metric tons.
By this reasoning, I determine that 1 hojillion = 1.66 / 0.0061 =~ 272
1500 Wh/kg is more than double what's been demonstrated for any battery chemistry even in a lab setting, and 500 Wh/kg is higher than any shipping lithium ion battery that I've ever heard of, so I'm going to say that your numbers are complete BS.
The bendable displays can only be bent in one direction at a time. Think of it as the shape of the screen being half a cylinder, when what you'd need to do what you describe is half a sphere.
Except it's not just the image that is distorted and needs correcting, it's also the focal plane. And to those of us with vision problems like myopia, the curved focal plane of the Oculus Rift means only part of the image will be in focus. You can't correct for focus in software.
TekSavvy leases more than just the last mile, they also lease the aggregation network. For users in eastern Canada, TekSavvy's entire network is constrained to a single building in downtown Toronto. As a Montreal TekSavvy user, my path to a server on the Internet goes through nothing but Bell hardware all the way until it hits 151 Front St. in Toronto, at which point it gets dumped into somebody else's network again (one of TSI's upstream providers).
Independent ISPs are not resellers, but to say that they're only getting the "last mile" from Bell is incredibly inaccurate.
Not really. The processors are identical, excepting the TDP share between the CPU and the GPU. The MBA has an Core i5-4250U while the SP2 has a lower-end Core i5-4200U. They're both 15W TDP parts with the same turbo clocks, but the MBA has a lower minimum clock in order to make up for the higher power draw from the GPU. In the end, considering how low power draw is at idle, that's not making a big difference. Besides that, if you put OS X and Windows on the same hardware, Windows consistently delivers dramatically less battery life. In that case, there are no hardware differences whatsoever.
It'd be nice if this wasn't the case, because I'm primarily a Windows user, and I'd rather run Windows on my MBA if the battery life wasn't so much worse than OS X.
OK, then take the 13" MBA's ~14 hour battery life and scale it down by the relative battery size difference, which gives you 11.1h on the MBA to the 6.7h on the SP2.
This isn't news, per the article, testing in 2009 on an MBP turned out results of 8.1h for OSX and 5.5h for Win7... It's been known for a long time that Windows has poor battery life (or, perhaps, OS X has better than average battery life). Either way, it means Microsoft needs to do something. Be it taking a deeper role in driver development, or investing the resources in OS-level enhancements, or whatever else is required.
There's ample evidence showing that Windows has substantially lower battery life than OS X even when running on the same hardware. I've personally experienced this myself (I've got a 2013 MBA), albeit with Windows 7 rather than 8. The point here is that even when Microsoft has full control over the hardware going into the machine (the Surface Pro 2), the battery life is still substantially worse than comparable hardware running OS X.
I don't think there's really much debate about the fact that Windows battery life is poor, and I'm not even sure that the reason why it's poor is important: hopefully the negative press about it will prompt Microsoft to invest more resources in fixing the problem. Perhaps they need to be more aggressive about background services, perhaps they need to take a more active hand in device driver development (even if only for the hardware they put into their first-party machines)...
Errm, what article are you reading? Because the one I see shows the Haswell-powered 13" MBA getting ~14 hours of battery life to the Surface Pro 2's ~7 hours of battery life. Sure, the 13" MBA has a bigger battery, but the 11" MBA has a smaller battery and still gets ~11 hours.
Your arguments about the Surface Pro 2 not really being microsoft hardware are not really meaningful, you could say the same about Apple's notebooks. They don't make the CPU, or the GPU, or the SSD controller, or the screen, or the display controller, etc.
And Microsoft has the exact same benefit of being able to tune everything in the Surface Pro 2. They're just as vertically integrated on that as Apple is on the MBA.
Same issues are seen between Surface 2 / iPad and Surface Pro 2 / Mac Air... Windows just generally has shitty battery life. Even when you run OS X and Windows on the same exact machine, the difference is substantial.
G-Sync enforces a 30Hz minimum refresh rate (the monitor will never wait longer than 33ms to refresh, or in the 144Hz demo monitors, it will never wait less than 7ms), so your example wouldn't work, but apart from that, yeah:)
Google likely pays far less than $0.60 megabit on average, because they're handling large amounts of traffic through public and private peering arrangements. They've got their own fibre to get data to the appropriate public IX. For example, all my traffic to/from Google goes through TorIX, regardless of if I'm talking to a Google service or a Google Fibre customer. Many of the local server and colocation providers are also connected to TorIX or QIX.
Couldn't you have gone with another form of pain management? There's topical anaesthetics, oral analgesics, even general anaesthetics...
When I had my wisdom teeth pulled (all four at once, plus four other teeth to make room in my jaw), I got a pretty broad spectrum of things. Oral sedative to help keep me calm going into the procedure, injected sedative to keep me calm during the procedure, topical anaesthetics to make the needles in the mouth hurt less, and then injected local anaesthetics for the procedure itself, followed by oral analgesics to manage the pain after the local anaesthetics wore off. You'd think that, if they couldn't have done any injections, they probably could have done the sedatives fully orally, and they probably could have dispensed some heavier oral analgesics to help during the procedure...
Errm, you're a bit off there. Rather than 4 hours and 43 minutes, a Tesla supercharger is rated at 20 minutes for 50%, 40 minutes for 80%, and 75 minutes for 100%. The other thing (for any plug-in hybrid or full electric) is to charge it overnight so that you start every day with a full charge. The automated battery swap would reduce that to a minute and a half, although those are similar in cost to a tank of gas. The 240v outlet is about right, although if you get an 80A one installed it's cut in half.
So, while I think that your idea about the practicality is wrong (a 5 hour drive would not require 4 hours of charging, but perhaps 20-30 minutes), I generally agree with the sentiment that the supercharger is not quite there yet. I think their 2015 projected map gets it most of the way there, which is probably good enough for long-distance driving for most people. I do hope that they continue to expand beyond that, though; it would also be useful to have the chargers *in* major cities. Not so much for people who live in those cities (because they can presumably charge overnight at home), but for visitors to the city; hotels don't usually have 240v ports to use, so it would be useful to get a full charge on the way out of the city.
So basically I'm saying "You're very wrong, but I generally agree with you that the infrastructure isn't there yet."
In Canada we have nfc built into our debit and credit cards making paying for items under $20 super easy.
If only it actually worked. The vast majority of stores either don't support contactless payments, only support one of the two (like payWave but not PayPass or vice-versa), or just don't have it set up correctly. "Oh, sorry, it's not working" is a regular refrain. Even when it does work, cashiers often don't understand it correctly. There's this one cashier I encounter regularly who, I had my credit card to her expecting her to stick it into the reader for a chip & pin transaction, and instead she waves it over the terminal. Which, of course, doesn't give me the opportunity to verify the amount I'm being charged until after the fact.
I've found it to work reliably and consistently at McDonalds and Jean Coutu, and the self-pay terminals at Canadian Tire, but I can't think of any other store I frequent that supports it reliably. At many stores I see terminals that say "contactless" on them, or the prompt that comes up is "swipe/insert/tap", but attempts to use the contactless feature does nothing.
NFC payments doesn't go on your phone bill, at least not in Canada. They're integrated with Visa payWave and Mastercard PayPass, so when you wave your phone at the payment terminal, it just pretends to be your credit card's RFID chip, and the effect is exactly the same as if you'd waved your credit card.

Well, I'm not the one with the problem with needles. Getting them in the palette is crazy uncomfortable, but in the arm is fine.
