I use my xbox one for Blu Ray which is almost never haba

I use Netflix and Crunchyroll through my consoles constantly. Probably equal to the amount of time I spend gaming on them.

Wouldn't make sense for me since I have it plugged into the same screen I have my PC on. And there isn't really anything on my console that isn't better on PC.

Yes, and I have for the last few years.
I've actually got rid of cable since Netflix has been available on my 360 and PS3.

I used to use my PS3/PS4 a lot for multimedia stuff but then I built a new gaming PC so now I literally only turn on my PS4 to play games.

Nope, gaming only.

Rarely, ps4 for youtube and browsing, ps3 for bluray, wiiu abd vita for browsing.

Xbox One I use for Netflix, Hulu Plus, & BluRay quite a bit.

Wii U I use for its Internet Browser sometimes. Usually if I'm looking for game guides or just wanna look something up quickly while playing a game.

I use to. My PS3 was the only bluray player I had for my TV. When the PS4 came out and dropped all the main functions, and didn't allow the PS3 BD remote. I bought a real BD player. And never use the PS systems but for games now. Plus the horrible support of files on the PS3 pushed me to Oppo. That thing will play anything you throw at it. Except 12 hr files. And is easily region locked disabled.

PS3: YouTube, Blu-Rays
PS4: Blu-Rays, WWE Network, IGN app, watching Twitch streams, browsing
PSV: YouTube, browsing

Note: browsing on consoles for me is limited to looking trophy guides, game reviews or other things related to games that I want or that I'm playing right now. I don't do it on PS3 because it's the only one of the 3 above that can't open the browser while a game is running.
