Nexus 7's Smart Cover-like magnetic sensors

Google's Nexus 7 tablet appears to have a feature that isn't showing up in any of the official specs. Over on YouTube, user wwscoggin showed off an experiment in which he used a magnet to discover a sensor that puts the display to sleep. Does this sound familiar? Yes, it's a function that has been used in the last two generations of iPad to allow the Smart Cover to switch off the display when closed.

The Nexus 7 is manufactured by ASUS, and the company has demonstrated a case for the device that is surprisingly like Apple's Smart Case. It's unknown if the ASUS case will take advantage of the magnetic sensor to pull off a Smart Case functionality, but if it does this may add fuel to the fire for yet another patent infringement case from Cupertino.
