Today’s a good day to get/install OS and browser updates on all your critical devices.

Consider turning off wifi on non-critical devices (putting to sleep is no longer enough because many devices still listen to or contact the internet while asleep) until you have had a chance to safely update their software (perhaps after software updates are available in response to pwn2own demos and disclosures).
