Comment Pretty durable in my real-world use. (Score 3, Interesting) 88

I have one that I've carried and abused daily for years, still working, though I think it's getting close to needing a replacement. My biggest problem, because I wear it on a necklace chain, is that it's been getting sweat on the contacts which eventually have gunked up and corroded. I was able to scrape it off with a knife, but that scraped off the gold plating and exposed the copper underneath, which is of course corroding much worse. I've got the private key locked away here somewhere so I can flash one of my spares and be up and running quickly, or I can just add the new key to the places I use it before it croaks. I've had more problems with USB ports getting worn out.

Let's see, I'm no mathematician (in fact I had to Google how to even spell it), but 40% every year seems like it couldn't sustain decades ... Someone better at math correct me if I am wrong, but to have a 'normal lifespan' of even 1 decade means no more than 10% loss every year (on average).

Sometimes it's better to not double-down when you're wrong. :)

"the problem with renting special equipment is you also have to have the trained personnel to operate it. mostly you are better off contracting the service of having the earth moved instead of renting the equipment to do it yourself"

This business is NOT about renting bulldozers to homeowners digging a basement. It's about renting bulldozers to a contractor who already knows how to operate them and has all the licensing (or has an employee who does), but doesn't have enough jobs that need dozers to justify buying one that will sit unused most of the time. By doing it as a peer-to-peer agreement rather than one company owning all the equipment and taking all the risk, everyone can make money.

BTW, one of the money-makers my HVAC installer mentioned was that they own a crane and have a licensed operator ... anyone who needs crane service can hire his crane and operator if he's not using it for his own jobs. He's be happy to have a third party deal with the bookings.
