Some very novel jobs where you need to be at a computer but also like to see the person in front of you? For the sake of transparency so the client can follow a bit?

I am just guessing. Transparent screens as tech are very promising for AR, imagine a technicians tablet with this? But a laptop… more a novelty.

Yes. The advantage is it's really cool.

You can get done damn near everything you need with super basic products, but is that how you roll?

So you can proudly watch porn in public and make not just people behind you uncomfortable, but also people in front of you!

Put a paper drawing behind the transparent screen and draw on the screen to digitize it.

Everyone in the circlejerk can look at the same screen.

Only and only use I can think of is tablet mode without relying on screen flipping somehow away from keyboard.
