Since @matigo et al. are posting about company security (I don't know if I've mentioned this before):
My company's security policies are so strict that no USB connections apart from mouse and keyboard are allowed. I assume they keep logs. Not a problem for most people, perhaps, but even the social media and marketing directors aren't allowed to connect USB devices…like card readers and cameras…which means that they have to transfer files wirelessly. No wonder that room always feels so gloomy.
