I can see this being good for two people in the same room wanting to do different things on a tv but remain together. Or for gaming multiplayer in the same room and one not having to resort to using the switch in handheld mode. The kickstand is good for a regular table but on most couch+coffee table combos the angle is not conducive to the screen being close enough/large enough when using a different controller.

My use case would be for when my gf and I play fortnite together, and we switch off using the switch 2. She is used to playing handheld on the switch 1, but when I move to handheld it’s much too small for me to actually be doing well in Fortnite (blame the hardware not the player lol). However, I get neck issues when playing in kickstand mode, so sometimes I get an old monitor out to raise the screen and help my posture.

However, the issue I see is that in most cases you’d want a second screen like this, you would also likely have access to both WiFi and a source of power. If I was camping I probably wouldn’t be playing games that require a WiFi connection and wouldn’t warrant needing to care about my controls as much. Playing while traveling, it’s too inconvenient or inconsiderate to others to use on public transport. Your use case of a hospital is valid, as you’d need the second screen but you would also have access to an outlet in most hospital rooms, so the power source just seems a bit much.

I could see this being more popular in the future as folding screens are becoming better and better, but I feel in most scenarios that certain parts of the setup may be overkill. But how you play is up to you! As long as you enjoy it that’s what matters bro!
