Seeing as how people are reporting some scratches on the screen, also from tear downs it's been shown the dock is basically just a large hunk of plastic.
It's also needlessly large I think, it'd be better if it was smaller and more portable for times where you want to take your dock with you to some one else's home or if you're going on vacation and wouldn't mind playing on the hotel HDTV.
A dock more like this I think would work better:
No way to really scratch the screen and easier to dock/undock I feel.
What's even the point of having that piece of plastic on the Switch dock? It doesn't really do anything but potentially scratch the LCD. I think Nintendo made the dock purposely bigger than it had to be to make it look more like a console component, but there's nothing inside that dock basically, it's a waste of plastic.
