You forgot the sarcastic marks. Unless you're serious, then maybe you don't know what Nook and Kindle Fire are based on.
It's a Japanese comic, the comic's name and the main character's name is Yotsuba. The closest comparison I can make is it has some similarities to Calvin and Hobbes, namely because of the age of the protagonist and precociousness. If you only read one, I would recommend Yotsuba. It's available translated into English.

The projection systems are only getting better

I think projectors have been pretty good for five years or so. I don't know why these makers show them on a table though. Hang it from a ceiling or don't project, as far as I'm concerned. The upside is that new visitors think you don't have a TV, the projector hides in plain sight.
Maybe they learned something from the marsupials and the TV has a pouch.

I guess if you watch movies in the dark a disappearing TV would be no advantage. But if you just watch TV shows in the evening with the lights on, maybe those black bars are a distraction, matching neither the image nor the TV surrounds (unless your TV cabinet is black of course).
As for the daytime, there is a kind of glass where you run a current through it and it goes from completely clear to completely opaque, sometimes used in car windows. Perhaps if they put a thin layer of this behind the image-bearing glass? They would need to find a way for the black glass to only activate in areas behind actual image though.
Sounds like an interesting idea, though maybe ten years from practicality. But I really don't see why the black bars are a problem in the first place, especially with people that are willing to ruin (stretch, crop, etc.) the image to make the black bars go away.
