I solely use Netflix on my Wii U. I don't use it on any other platform. Not my PC, tablet, TV, Bluray player, 360, Wii, 3DS, etc.etc.. Nothing else. I used to use it on my 3DS, when I traveled, and didn't bring anything else with me. Well, I still do, but not nearly as much, as I have a lot of games I still need to beat on it. But, anyways, yeah, I love Netflix on my tv. I love the fact that I can watch Netflix on my Gamepad or tv as well. I can lay in bed at night and watch Netflix on my Gamepad while watching something else on tv. Or, I can sit at my desk and have Netflix on my Gamepad while I browse on my computer, with my tv on. (I like to multitask, I don't know why, but I do). But, when I binge watch Netflix on tv, like if I'm watching through episodes of a tv show, I can sit comfortably on my couch, and watch the show on my tv, and then control everything from my Gamepad. Or, while on the couch, if I'm watching a movie, I can be cycling through other movies to watch while the first movie is playing, and pick what I want to watch next before the first movie ends, so that when it ends, boom, I can just go straight to the next movie, without wasting time between movies trying to figure out what to watch next.
So yeah, the Wii U is basically the only way I go now, when it comes to Netflix. I may watch it on the 3DS, if I travel, and it's the only device I have with me. Tho, that's just not the same. However, when I finally have my 3DS-XL soon, that should look/feel better, when on the go. But yeah, I don't use Netflix on the PC or any other device. Wii U all the way, for me.
