The argument I would make is that at this point in time, if you don't own a 3DS...why wouldn't you just buy a 3DS over a Switch? It's less expensive, doesn't require any additional costs outside of buying games, and has a great library to choose from.
The Switch literally only has Zelda, and even that is virtually identical to the Wii U version.
I am optimistic about the JoyCons. Supposedly the HD Rumble is great.
How ironic that Nintendo is taking shots at the very product they require you to use in order to voice chat.
