In a somewhat sudden announcement on Twitter, Nintendo has revealed you can finally download YouTube on the Nintendo Switch. I've been using it and it's pretty much the same as you've seen on other consoles. It does, however, have touchscreen support which is neat.
All-in-all, it's great to finally realize what the Switch was made for. Watching Vine compilations on a Nintendo Switch. What do you mean there are also some good games on this thing? What's a Zelda?
