Nexus 7 looks to have a magnetic "smart cover" sensor

The Nexus 7 is shaping up to be a pretty cool device for $199, and one feature that doesn't seem to have been talked about, or mentioned by either Google or ASUS, is a magnetic smart cover sensor. Considering its a pretty nice feature, one would think that either company would've mentioned it by now.

All you have to do is place a magnet near the front of back of the Nexus 7 along the bottom left-hand side while in portrait mode with the display home, and you can see the results for yourself, or in the video below:

Google do sell covers for its Nexus 7, but it's not known if they support the "smart cover" feature. Could Google or ASUS not have mentioned it, so they didn't get caught in Apple's lawsuit-frenzy? This could be tapping against their patents, but Apple's focuses more on its ability to latch onto the device itself, rather than turning its display on and off. We shall see.
