No doubt it's a great app for Chromebook, it shows most of the stuff in one place. The one thing that i missed here is internal storage. That should also be mentioned here. Also in network section, it should mention that if the device support Bluetooth, Lan, Wifi with yes no kind of table that will become a great plus.
