I guess I'm much more worried about "the cloud" aggregating lots of people's data on connected machines where hackers can score big with a single vulnerability.

I guess I'm much more worried about "the cloud" aggregating lots of people's data on connected machines where hackers can score big with a single vulnerability. The recently-exposed NSA firmware hacks seem like they require per-target effort, and since I'm neither wealthy nor wanted by Mossad, I don't see myself being worth that effort. (EDIT: e.g. stealing $20 apiece from everyone affected by the Target data breach equals big bucks, much more than bugging the firmware in my laptop and trying to clean out my bank account.) OTA firmware updates being signed would be a good thing, but I'd rather spend the time and energy keeping more things local, and avoiding the "internet of (broken) things."
