All the commenters above seem to think it's useless. The market is clearly saying that there are more people who have a use for it than there are Pi Zeros available. Raspberry may be guilty of poor market planning and the zero may not be useful to some people, but it darned sure seems to have surplus demand.
Me? I'm looking at the hacks that allow me to solder an old wifi dongle to it, or the one that lets me run it on Power-Over-Ethernet (yes, different applications, although wouldn't it be cool?!).
"The highway works as long as nobody drives on it?!"
More than 80% of their speed, more than 90% of the time. So, let's say that 10% of the time it was at or below 80%. Now let's say that a day has 24 hours. So only 2.4 (call it 2) hours of the day was the connection more than 20% below advertised, possibly much more. Now let's say that that occurs when EVERYONE IS USING IT. The system fails under peak load, i'e. when it's being used. So most users will experience failure.
Would you accept internet that is completely nonfunctional from 6-8PM every day? That satisfies your criterion above.
It's not like nobodies using the system when it's down. The system is down because it's being used. This is not an acceptable failure mode.

I'm pretty sure that should be <500kB of advertising.
Yep... mea culpa. As soon as I saw it go up, I cringed and went wildly searching for the edit function. And the sentence before that should read: ".. took 10-30s to load 10-20MB
Most users don't want to have to relearn how to do stuff just because some hipster decided their way was so much better.
It's just text, people. It doesn't need flying toasters or 3 dozen modes.
It's infuriating as an expat to try to get content in the language I want. Yes, there are solutions, but almost all are technically illegal one way or the other.
I have to admit, I just flew Milan to Heathrow to Denver, and back, and I don't think I looked out the windows once, other than while standing in line waiting for the bathroom. Granted, I was center section aisle, and I did enjoy gawking on a recent flight across Africa, but overall I'd happily trade windows for a GOOD set of cameras.
In other news, BA finally update the entertainment system on their transatlantics to something better than 480P. Which also helps!
Pretty much any cheap plane will work fine. I believe I recall a 74 being used a few years ago (https://en.wikipedia.org/wiki/Evergreen_747_Supertanker), and C130s are very common in this service.
Once you've done this with it, though, you'll probably never see it back in commercial passenger use, anywhere. Dumping 48000kg while in the middle of a dive puts some serious stress on the airframe (YouTube, not for the faint of heart).
