I would love one of these displays that integrates smart film for a real "frosted glass" look. And since it's smart film, it'd be able to become totally transparent too.
Gimme a real physical keyboard though, and no "AI".
The thing is, for the privacy aspect, I'd need the frosted glass look to only work from my side of the display. Even a blurred/frosted display leaks way too much information if parts of it is high intensity colour up close.
Maybe if it had dual screens and cameras so it could be made to look as if it is translucent from both sides but the 'outside' is faked however you want it to be.
