Minus the dual screen of the Wii U, which was awesome. It'd be cool if the Switch 2's dock could work independently of the console, so that you could have a reverse Wii U- experience with it. The dual screen setup can be a neat gimmick for gameplay, but it's biggest strength is the convenience that comes from having a second screen closer to your face. You can have less visual clutter on the main screen, and reduce the amount of menus players need to click through.
