That's just a piece of plastic that connect the Switch to the TV so those who have the NS on its own probably prefer its portability than buying a second Dock. Just seems strange they'd do this. It would be a good idea if Nintendo sold the Switch separately but that won't happen. The Dock's retail UK price is £149.99 so taking that into account, the Switch could end up being sold for only £130 without the Dock but again, not happening in the slighest and that's because they have it advertised as a home console which very much is. On a hypothesis, they could have "Portable Edition" with the Switch + Joy-Cons while also having the normal "Console Edition" with the Switch + Joy-Cons and the Dock. Anywho, still haven't connected my Switch to the internet 'cause of Zelda taking all the gametime.
