That basically shattered my dream of leaving my work laptop at home on short business trips. Well, that and it weighs as much as a laptop anyway so there wasn't actually a benefit.
The incredibly loud mechanical timer drove us all nuts. We always forgot to change the heating element (#slices) selector, so invariably ended up with one uncooked piece of bread. The pop up function is beefy but difficult to get escape velocity on small items. They eventually ditched it and went back to a £20 long slice Cookworks from Argos. They still have the Aga (also bloody annoying).

If enough of us are saying Tetracopter, it will stick.

It does occur to me that taking my shopping list on the phone to Tesco and putting things in a basket manually is probably not the future that Bezos had in mind for Alexa. But ultimately I don't trust Alexa / Amazon to actually do the buying.
I don't game, so don't care about ping.
So, where I am, using 4G for my home internet is faster and cheaper, and I can gift data to my phone. I have not had any issues with reliability.

A few years ago I saw a talk by an industrial chemist, long distance power transmission over carbon nanotube cables. Looks like they're still not ready for primetime.

1. Short installation window: they can only install this machine when the tides are changing (i.e. not much flow), so they only have a couple of hours to collect the moorings and it hook it up to the grid
2. Fatigue: loads of areas, not just the turbine blades... variable loading on the mooring lines, vortex induced vibration of the power offtake cable, wave induced motion on the offtake cable
On the two you mentioned:
Marine growth (barnacles etc.) is generally manageable with anti fouling paints, or PTFE (teflon) coatings, wipers and bearings around the things that you don't want to seize up. The animals will have a hard time getting a footing in this high flow environment anyway, it'll be pretty well self cleaning.
Saltwater / corrosion is also manageable with coating systems, cathodic protection and large corrosion allowances.
While these two do cause issues, they're kinda "solved", you can generally apply the same straightforward techniques and they don't take up as much engineering effort as solving the installation, system design and fatigue.

And it's a hack, but you can put text comments inside an N() function and add them into your formulas.

Reason it's done in pdf is a lot of our technical is spat out in PDF format (generated from CAD - SolidWorks).
There are other options like Traceparts or setting up a variable input SolidWorks model to generate loads of static outputs, if you have the time and money.
