This design is open-top. That allows sneezed droplets to fall in pretty easily. Whether or not that's a problem will vary by hospital, but some of them simply tape up the gap.

Aside from that, it's pretty nice.

Thanks for that link; the article was solid.

It's the scale of China's monopoly on rare earth metals which scares me. I'm -very- happy that mines are re-opening in other countries, and I hope that they're around long enough that home-grown manufacturers become reliable customers.

But they simply won't have enough mines and production capacity to secure the supply. Molycorp is small enough that China can flood the market with cheap rare-earth metals just long enough to mess up their $753 MM investment in that mine and knock them out of business again. This has happened before:

http://www.ndu.edu/press/chinas-ace-in-the-hole.html "The Mountain Pass rare earth mine in California, owned by Molycorp Minerals, was once the largest rare earth supplier in the world. Through the 1990s, however, China's exports of rare earth elements grew, causing prices worldwide to plunge. This undercut business for Molycorp and other producers around the world, and eventually either drove them out of business or significantly reduced production efforts."

Of course Chinese manufacturing temporarily loses that "access to rare earth metals" advantage if mines ramp up exports again, but if doing so can cripple foreign mining operations it may be strategically worthwhile in the long term.

China will rule electronics for the foreseeable future. Even if its advantage in labor costs were eliminated, China's parts ecosystem, lax recycling regulations, and (increasingly exclusive) access to rare earth metals will keep it on top for some time to come.

Their manufacturing technology is also arguably the most advanced in the world. We can't assume that another player would win if this were just a technological problem.

I do the same thing. Apple is unclear about this, however. ApplicationSupport is at /Library/Application Support, and /Library definitely does get backed up to iTunes.

That said, I think we're in the clear with respect to iCloud backups:

"Devices with an active iCloud account have their app data backed up to iCloud at appropriate times. And for devices that are plugged into a computer, iTunes performs an incremental backup of the app’s data files."

It's ambiguous. But "app data" sounds like documents, whereas "app's data files" sounds like big data files in /Library to me.
