Agreed. It's the same thing with the way they sell laptops or phones. Why leave dumb units lying around? Why would anyone ever buy a device that they haven't tried? Best Buy (as well as other stores) need to have well-functioning devices turned on and available for customers to try.

Additionally, they need their employees to go around and reset the devices to ensure a proper functioning system instead of the ones bogged down by apps/content downloaded by random kids onto the device.
