I feel this is rose-tinted.
Used all the Windows versions extensively, from leaked alpha builds to preview server versions and everything in between.
Windows 10 is the best version in my opinion, and before that Windows 8.1, and before that Windows 7, before that Windows XP, and before that 98SE, and before that 3.1
My metrics are hardware support, first hand experience with BSOD, maintenance effort, and most critically: how often does family bug me with technical questions per year. Since Windows 10, the latter has dropped off to 0 calls each year.

Thanks for this info. However, my point is why would they be invisible by default? What idiot thought that was a good idea? The same one who thought hiding file extensions by default was a good, secure, idea?

Since we don't seem to have a hardware forum, I'll ask this here, for those in DIY electronics.
Exactly how good is USB for providing power to a device? I specifically mean devices that are not attached to a computer and use the USB cable strictly for power.
I've long felt that we need a standardized low-voltage DC power source coming right out of our walls, much in the manner that we currently have 120V (or 220V) AC coming out of our walls -- to eliminate the need of all those "brick" power adapters cluttering our power strips. The last time I discussed this publicly (about 10+ years ago), I was scoffed, with the reason being every device uses a different voltage. (I rejected that, as AC devices were able to adapt to use 110V, so DC devices could adapt to use the standardized voltage).
The real problem was that every device used it's own plug size (and selling the proprietary adapter was a profit center). However, now there's some movement to power things with USB cables.
So, the question for the electrically minded here: If all you had available to power your device was an USB cable, would that be viable?
Truth,
James

For basically anything but a power amplifier or kitchen appliances, yes.
Latest versions of USB-C with Power Delivery can move up 100W and is used for powering laptops nowadays.
Here[^] are some ICs if you want to play around with it.

I have USB ports on my keyboard (lame) and ones on the computer (better). And some on power bars / chargers (best).

I don't think USB ports on the keyboard is lame. In the early days of USB, I loved it, for a few reasons: Computers had too few ports, so when you got yourself a USB mouse, and a USB card reader residing on your desk, plugging them in "locally" was great. If you must run separate cables for both keyboard, mouse, card reader, scanner, printer ... all the way to your PC, your mouse has seriously limited freedom of movement, and you have enough cable spaghetti that all you need for an Italian meal is the carbonara sauce... In those days, PCs made noise - my early tower PCs resided in a noise chamber, and getting at any of the ports were a hassle. So when I made a PC corner in my living room, I drilled a hole through the wall for the cables and put the PC itself in the neighboring room. To plug in another USB device in the computer (directly), I must leave the room.
Nowadays, I have a wireless keyboard and mouse (with full freedom of movement), so the "local" USB ports are in my screen: That is where I plug in the keyboard/mouse dongle, but most of all: where I plug in the memory sticks and the 'passport style' portable USB disks. I plug in my smartphone there, both for charging and for transferring photos to the PC. Sometimes I even plug in my full blown SLR or video camera for transferring a handful of photos or a couple clips to the PC, but my current screen only supports USB 2.x, so for lengthy videos or scores of hi-res photos, I take the bother to go to the computer and read them through a USB 3.x port.
If I still were on a cabled keyboard, and my previous screen that didn't have USB ports, I would be very happy to be able to plug in memory sticks into the keyboard, and to have mouse and keyboard connected to the PC with a single cable.

Mine are "lame" because, in my case, they were under-powered.
I think my (MS white) KB is at least 10+ years old ... it has things like: "My Computer", Calculator, Sleep, Mail, Volume, web navigation, media navigation, on and on.
YMMV.

Are we not there already?
I power devices from USB A sockets in my car (in my old car, I had a cigarette lighter adapter with three sockets). My last two cellular phones came with AC adapters with USB A connectors (and the last one of those I bought early 2016, the one before that must have been about ten years ago). I recently bought a charger adapter with three high-power USB 3 A sockets and a USB C socket (I bought it together with my keyboard because I thought I needed the adapter for charging the keyboard, without knowing that the keyboard would come with an A-to-C cable - but it is nice to have a high power 75 Watt charging unit in any case.) Neither of these have any hub functionality; they are all plain chargers.
For low-power devices, USB has been The charging standard for years. The power supply may have A or C sockets, but it seems like A will be the universal one for many years to come.

The Three Gorges Dam in China have DC transmission lines that transport power to homes, businesses, and such. There's even a (short) HVDC line going from Pennsylvania to Long Island. Historically I think it's been a matter of AC's efficiency over long distance.

I still see it coming into the house as high-voltage AC, with the longest run of DC being 10-20 feet within the house. The conversion would be done in the wall socket, so instead of two 110V outlets, it could have one 110V and two or four USB outlets.

Yes, exactly that. We have all the parts in place. We just need to convince people(*) to start using 'em.

What's the problem?
My plan (currently being built) is to give my home a 12VC spine along the middle wall, with ribs to both sides, with fixed cables to all room lights. For plug-in consumers I standardize on BNC connectors, cables with BNC in one end, whatever in the other end. It will mostly be plugs with standard 5.5 mm outer diameter add 2.5 mm inner diameter, but I have a couple devices wanting 2.1 mm diameter, so they need another cable.
I am installing 3-pin BNC sockets in my power rails, having 'declared' that the left connector supplies 12VDC, the right one supplies 5VDC. For now, all my 5VDC consumers use USB charging, from a hub supplied by 12VDC (unless supplied by the 75W AC based charger). I am not certain that I will ever provide any advanced 5VDC supply though my spine/rib network, even if the cabling is there.

AC-DC arguments are as old as the Edison-Tesla wars ...
Today (but at most for a couple decades) we have had DC-DC voltage converters with losses at a level that make them viable for general use. They are used in specific application, such as adapting the voltage from the PC power supply to that required by the RAM chips, but at the current, we do not have units converting from, say, a 750 VDC inlet to the house, to the 12 VDC expected by your tabletop radio, your USB hub or external PC disk.
For long-haul high-power lines, e.g. between Norway and Denmark or England, DC is the rule nowadays. But at the home level, it is still far easier to use traditional (or somewhat untraditional switching technologies) to transform household AC to whatever low-volt DC you need there and then.
Don't forget that required cable dimension is a direct function of the current, not the voltage. If you replace a 240V supply (regardless of whether it is AC or DC) with at 12V one, the current increases by a factor of 20, and you have to dimension you cables 20-fold! You will never get a 12 VDC power supply from you power company - that will be the day they come to install a railroad rail as the power connector to your house!
20-doubling cable capacity can only be done in short stretches. Like what I am now currently building in my home: I will have a 'spine' along the middle wall, both in the basement, first and second floors, with 'ribs' to the power consumers. The spines will be 6 sqmm conductors (I considered going down to 4 sqmm, but decided I didn't want the voltage loss), with 2.5 sqmm spines.

Well, it totally depends on what you are powering, but for many things it is totally viable.
For example, I built a device that runs off my USB port that is a Arduino pro micro (with ATMega 32u4) which emulates a HID (human interface device) --in my case keyboard.
Take a look at this snapshot of it running on my computer[^] right now.
The item closest is the Arduino pro micro. The item at the back is soldered to the basic UART on the pro micro and is a Bluetooth (BT) device.
I can unlock my computer from my phone.
My Android phone (via app I wrote)
1. connects to bluetooth
2. sends password (encrypted over BT)
3. pro micro forwards the bytes sent as keystrokes on my computer (via HID)
4. unlocks my computer
It all runs off low voltage 5v powered off one USB port of my computer.
I even wrote this up as an article here on cp: Ending the Era of Weak Passwords: Never Type A Password Again (Never Memorize A Password Again)[^]
And even better here: Never Type A Password Again (The Continuing Saga)[^]

Yes; these days, it does.
Years ago, some kid asked me to charge his phone on USB and naturally agreed. It was at 3% when he unplugged two hours later and started walking. (USB was up and coming those days).
USB, the "one universal" connector that fits all, comes in many shapes now. These days, my 10+ years old smartphone charges in an hour. I got a bunch of USB to USB converters, since USB on the PC isn't USB on the phone. If the kid would ask now, he'd have his phone completely charged in that time.
And got one of them "no plug" recharger-stations as a present. If recharches phones bloody damn quick, without connecting a cable! To me, that's magic. Or more realistic, it is physics I don't understand yet.
But from the looks, they can draw a lot of power, even if the PC is actually turned of. My keyboard does the same, it keeps displaying this RGB backlit even if the PC is "off". Push any button, and in seconds there's a login.

You could of course look up the power that USB3 provides, a quick Google would provide that. Including on which pin, and how much m-amperes.

One factor (although not the only one) killing SCSI was the bewilderment of cables. When I went to the computer shop to get a conversion cable for my eight SCSI 'standard'  plug, and the salesman made a sigh: You are lucky - we have fourteen different SCSI standards! - then I called it a quit. No matters what other advantages SCSI might have, I will never cope with fourteen different plugs, not even if they are compatible at a higher level!
The bewilderment of mostly needless USB cable variations point in the direction of the SCSI demise. We have created a mess that can't survive. The 'micro B' was a worthless sidestep of no benefit. The great marketing benefit of USB-C was 'you can put it in in any orientation that you want'. World-shaking news! Try to convince British guys that if they had stayed within EU, they would have been happy to get grounded AC plugs that could be turned 180 degrees when plugging in - that would be great, wouldn't it? (Those Brits never realized what they lost in Brexit!)

Unrelated, but try as they would, the EU is going to block it. If they succeed, more countries get the same idea, and thus we been blocking and torpedoeing all. We can't allow that to be a success.

Those Brits are about to become Hong Kong near China. A free port, near a closed mainland. They'd grow, whatever our "deal". So, we hurt them as much as we can, hoping Italy doesn't follow.

Luckily, we have USB now.

Think transformer without an iron core, with one winding in the plate, and the other in the phone.

Well I'm more a hardware guy than softwares so I can probably answer this from a different perspective. While low power coming from the wall sockets is good for things like mobiles and some plug in lights and some other things you can get issues when say a TV or monitor need a supply that can be 'altered' to allow then to work (a flat panel screen uses 1000's of volts, scary but current is so low to be not dangerous unless you want flash burns). While displays can be made to work of low voltage they are not that robust or long lived. House hold appliances which need 230/240 volts at 10 - 13 amps forget about!. I think the issue is down to good for some(alot) of things But mains power is needed for other things to make them efficient. Also high power DC not safe in the slightest (despite Edisons claims) if there a short on a DC power line you usually get somke and damage to the circuit board and wires connecting it, AC a pop, blown fuse, maybe a skid mark! Also getting zapped but AC not good, I have the scars from an AC zap that if it was DC would have more than likely killed me. AC good, DC bad. So I think USB is really a non-starter.

Well, I don't see it as a complete replacement for household electric needs, just those which require low voltage/low amperage.
