It's a niche usecase but it does speak to me - I struggle to be productive on a little laptop screen and would love to wear something like this not at a cafe but at a co-working space. The kind where you don't get a screen. If enough people do it it won't be embarrassing. I can also see the utility for digital nomads.

On the other hand, what I'm really looking for there is, my laptop in a virtual screen - and that's all I need. A wired/wireless headset as a peripheral for my laptop is what I need and these exist.
