My case provides more or less the same functionality at less than half the price ($16.99).
I can prop my N7 up to watch movies, type with my bluetooth keyboard, charge my N7 and hookup my headphones. All for a much cheaper price.
Now, if it had a way of providing an HDMI output, that would have been different. But, that's not possible since it has no way to push the video signal out to the dock.
Plus, this would require me to take my N7 out of it's case just to get the same functionality that my case provides me.
No thanks!.
