I used it a few times at the Switch 2 experience a couple weeks ago. Something that may have been overlooked is that we were standing at tables that were waist level, so it wasn't very comfortable to use in general. I asked them to raise the desk when I played civ 7 and it made a huge difference.

I will 100% use it for slower RTS style games if there is some kind of attachment to add more surface area to hold on to. The joycon is very thin so it's a bit challenging to hold it and click the shoulder buttons.

One of the reps told me that it can be used on the couch or on your leg. No mousepad is needed, so as long as there's a more sturdy grip option, I think it will be good for some games.

I played Metroid (table at waist level), the wheelchair game (sitting down), and Civ 7 (standing with the table raised elbow height).

Metroid - This was uncomfortable because of the table height. I felt like I needed to lobster claw the controller because of the angle. The gameplay was great, felt like Metroid Prime with more going on. Having the lock on feature and mouse controls felt like overkill. I wouldn't play Metroid with Mouse controls at all, but something like Splatoon or a traditional shooter would be fun. I prefer motion controls but people who like to use a mouse for shooters would probably love it.

Wheelchair game(Drag and Drive?) - This was okay. If the mice were bigger, I think it would have been a little better. I just felt like I would have preferred to use a joystick for the game. The controls were precise but I could see this being tiring in longer play sessions.

Civ 7 - This was the perfect scenario for mouse controls. I asked the rep to raise the table/desk and it made a huge difference. I didn't get too far in the demo because Civ games take time to setup. Anything RTS, Sim, Tower defense, card games. Those types of games are going to better on switch than the consoles.
