Edit: also I don't think it's that niche. I see this being a common occurrence in any household with only one high end TV and more than one person who wants to use it. The price point isn't much more than a controller and a screen to begin with. They should sell the remote play hardware without the screen (just hdmi out) and controller (just include a bluetooth chip to allow controller pairing) at a lower price point to appeal to a wider market (cause portability in the household seems less useful, but just using another TV seems more common)
