"Microsoft will continue to keep it current for the supported lifetime of the device"
Er, what does that mean exactly? I've got working devices over 10 years old...

I find it hard to believe that replacing a copper wiring loom with an aluminium one will save enough weight to make a measurable difference to fuel economy. It's filthy stuff to make a good connection to, too - we have aluminium phone lines round here, thanks to a copper shortage in the 70's, and BT are forever re-making the connections in the local junction boxes, due to corrosion.
A much simpler way to improve economy is to add a small measure (0.2%) of acetone to the fuel. This reduces surface tension and improves atomisation, with a resultant smoother burn. I've used this in two cars and one motorbike, with an overall 8% improvement in economy. The bike, in particular (as it's a twin) runs more smoothly and is more tractable at low revs. I've been doing it for some years, with no ill effects or damaged seals. It works with petrol and diesel, but increasing the amount does not help - I use 20ml per 10litres.
"a heat exchanger that heats the engine oil"
Seems a bit unnecessary - the engine will warm up the oil directly, as the author later admits. Also, if the thermostat is working properly, water will not be circulating when cold and the pump will have relatively little to do. Centrifugal pumps are loaded by flow, so not inefficient.
It is complete nonsense, of course, and relies on the electrical component representing zero, even though most of that will have come from the burning of fossil fuel. And how much of the calculation assumes electric power? It must be more than half, which is very unlikely to occur in practice.
As for cars under £95k that better 4.4s, try a Caterham Superlight R500, which costs less than half that and gets to 60 in under 3s. In fact, in 4.4s it could probably get to 60 and back again!
I believe this is already approaching in Norway, where there has been a greater uptake thanks to the generous subsidies, which are becoming unsustainable. Their government is now claiming that they didn't say it was permanent (although I suspect they didn't say it wasn't, either) and things will slowly revert to normal as the tax breaks disappear. I certainly wouldn't want to be stuck above the Arctic circle with a dead battery...
I hope the Dept of Energy (and Climate Change!) has done its homework, as it seems to be encouraging us all to use electric vehicles while simultaneously closing power stations at the behest of the EU. Charging an EV at home will at least double your consumption (more if it needs frequent full charges), which is hard to reconcile with the present 2-3% capacity margin that has already resulted in this: http://www.bbc.co.uk/news/uk-england-devon-22845487
Service stations are going to need their mains supplies upgraded if electric vehicles ever become popular (and vice-versa), especially when a 'fuel stop' may take a couple of hours for each EV. I know Tesla's 'supercharger' can do it in 30 mins, but how many 120kW outlets can you install without your own sub-station?
"Let the machines do what they do better than humans."
Which, as the piece explains, is not driving. Driving in real-world conditions involves all kinds of skills that don't automate: the necessary eye-contact you make at crossroads or pedestrian crossings, the judgement required when negotiating a narrow road or deciding when a verge is safe to put your wheels over, driving past rows of parked vehicles, dealing with unexpected situations/roadworks/breakdowns etc.
I can see that it might ultimately be possible, in areas where there can be only that type of vehicle, but a mixture of robot and human drivers sounds pretty scary to me.
Three facts, quite easy
Should be known to all
Would-be arrivers
Who set out on wheels:
That roads are greasy
Safety margins small
And fellow drivers
Fellow imbeciles.

WRT Beats phones, this is far more to do with branding than sound quality. I have some JVC 'flats' (small 'on-ear' phones) that sound as good as, and are vastly more comfortable than, the Koss ESP-9 electrostatics I bought 40 years ago, for what would now be over £2k (I was single then). The JVC's were £20 when I bought them, and since my son has now requested his own pair, I find they are available on Amazon for a fiver!
"they leave the MSE icon at a warning red even if it is up to date"
I thought so, too, but my son's XP machine (which spends most of it's time connected to Steam) has MSE and it is currently showing a green icon with tick, and says it's up-to-date and protected. I've no idea why, unless MS got tired of nagging everyone.
Have just read Mister Bee's message, so will try that the next time I get an opportunity - perhaps the Boy knows more than I thought!
"a loaded mass of about a tonne" (said the chap with the Aygo)
Actually, the lift motor only has to cope with the weight of the occupants, thanks to a counterweight. Still a fair amount of grunt required, though, and I'm really not sure about the pressurisation, intended to prevent ear-popping. Won't that be much worse when the doors finally open and the people waiting to go down are blown backwards..?
Even 10% (which seems a low estimate to me) of a very large number is still a large number. Come April 9th, when the sky hasn't fallen in, most XP users will just carry on as before, but without the nagware.
My 15-year old Toshiba laptop (upgraded from Win98 to 2k) was in use again last week, queuing up and playing sounds for a local theatre production, as it has done for a decade. I'll change it when it breaks.
