Was just talking to a lab tech at a hospital.

It seems that some of the newer lab machines require internet access because you can't run lab tests unless you have a paid subscription to use the machine. No credits on the subscription, no tests.

I mention this b/c a lot of commenters here are saying "but why would you ever hook up a freezer to the internet??"

I find that type of comment fascinating as many of the people on HN worked for firms that built the technology required to use internet based subscription models.
