Is it even useful as a faceplate? An active display would be way more accurate at displaying hardware stats when the machine loses power (it'll shut down).
This screen is entirely independent, with its own power source, so unlike most bistable screens this one could also report when its connection with the Machine is lost, and in a different way than simply turning off.

My kindles usually show a dead battery graphic when I get back to them after a long time away... With enough power storage and the right trigger, this could be done.
On the other hand, you probably don't want that glow of an active screen all the time. Status LEDs are annoying enough.
