The only issues I have with the Switch is how loose the dock is with the console itself. It wobbles too much when you try to take it out, when it should be snug in there, like a game cartridge.
The other one is the AC power outlet has a large box at the end. No AC cord should have a box on the end, where you plug it in an outlet. If you need a box, do what the X-Box 360 did, and put the box in the middle of the cord.
