I got a small scratch on my screen from the dock during the ten days or so between buying the Switch and my screen protector arriving. It's not a big deal now that it's protected, but I don't know why anyone would want to risk using it without one.
The whole situation makes me hate how joycons don't have a charging plug. I only play in docked mode, and the only reason I had to constantly take the device out of the dock was to charge them. I have a Pro Controller, now, so I'll only use the joycons for multiplayer games, and I'll eventually get a power dock for them.
Wait...why did you have to take the switch out of the dock to charge the joycons?
