I've been trying to think of use cases since I read about this a few days ago. I can't think of much, especially in laptop format. However, if you go beyond laptop into larger screens:

- A tv that becomes mostly invisible when turned off would be nice (I think I saw a tech demo recently?)

- A conference room screen on the central table but invisible until turned on would be a step towards the holographs you see characters meeting over in scifi movies. However, I'm not sure how much actual utility it has beyond cool factor - especially since all the text will be mirrored for those standing behind it

... and that's about it. The idea that you could put something behind the screen and sketch it which I've seen floated sounds kinda dumb. Much easier to just take a photo and draw over that.
