There's really no lack of devices with which to watch Youtube these days, but now yet another option has been added, which is the rumoured (and leaked) Nintendo Switch. The app is almost 100 megabytes in size, and has basically all the bells and whistles you can expect, although it has fairly limited touch controls.
It's free to download from the Switch's eShop, and Nintendo itself hasn't made much noise about this at all, except via a tweet about it.
Will you be watching YouTube on your Switch?
