For anyone else confused by the headline citing one price and this comment citing another, it turns out the difference is between the "Mini Lite" and the "Mini" - the Lite seems to be connected to a computer all the time, and thus has no on-board compute, no accelerometers, no WiFi, and only half the microphones. My suspicion is that the $299 one is for playing around and the $450 one is if you want it to chase the cat around while you're at work
