Bathroom scale: lovely it powers up when you tap it, but eats up 2 button cells a year for a few dozen uses a year
Kitchen scales, bit more use, at least once a day but again 2 button cells a year
electronic caliper: Same, eats up 1 button cell a year, just sitting in my toolbox
Strangely enough none of our kids toys with batteries seem to suffer from this problem
How much extra cost does a hard on/off switch add to the bill of materials?

I use these on a regular basis, for urban environments, electric busses combined with overhead superchargers at the end-of-line terminals work really well.

A Free Electron Laser EUV source would be a facility on it's own, similar in size to a small powerplant built adjacent to your fab, and multiplexed to a dozen or so EUV wafer scanners, that's quite a different endeavor.
The good: they're definitely cheaper, I paid about a third of the raspberry Pi 2 price for a comparable Orange Pi. Other models seem to have similar aggressive pricing.
The bad: Armbian distros are a mixed bag, I had the impression some of them were put together by developers who didn't even have the particular board on hand. I spent a good three hours just getting WiFi to work (not being familiar with linux didn't help either though) , while putting up with an invisible cursor editing config files. Setting up a raspberry pi zero W in comparison was 5 minutes. Also I found out later that the pin header was 180 degrees rotated compared to the Raspberry, which made it not compatible with standard hats.
In retrospect I did learn a lot, and the Orange Pi has been running without issue for 2 years now. But Raspberry's have my definite preference.
Running a modern CPU with an acceptable TDP, means only so much of the transistors can be utilized simultaneously .
Now that the hype over the original Glass release subsided, there are actually some promising developments for the enterprise market. Notably Augmedix, a company aimed at optimizing doctor-patient interaction uses it as a tool allowing for remote medical assistants (https://www.augmedix.com)
However, the research did find it's way into telecom, high speed multiplexing switches, with massive bandwidth in a compact formfactor would not have been economically viable without photonics.
