It's just insidious though isn't it? There's a scare that we might have internet connected energy meters. You end up with dozens of devices that have connectivity and you don't actually know what they do. I have a satellite box, that I manually connect to the internet every once in a while for on demand services. But I have no idea what information it sends back. Could send back my entire viewing history for all I know. Or rather it might be collecting and storing data to later send.

I noticed my satellite box trying to pull a web page from my computer. Malware is another problem.
