Yeah that is my point, I can use youtube for free on my PC, yes it would be nice if I could use it on my Xbox 360 though I don't know how much use I would actually get out of it other than a random use or 2 here and there. But its not something I am going to pay to use when I have my PC within arm's length of my TV. Same with Facebook, Twitter and whatever else they offer. The TV apps are pointless if you already have a cable box, andi if you can access those apps you probably have a cable box. Not to mention I have an iPod touch, which means I get all those things in the palm of my hand while playing Xbox. When I am on youtube I rely heavily on the sidebar to search for videos that I might want to watch after I get into a category or group of things I want to watch, and I don't know if the Xbox offers that feature. But that feature is essential to me.
Besides with Tudou and Youku I really don't use youtube anymore, they delete too many videos while Tudou and youku keep most of them and have a wider selection of things that I want to view.
As far as Gold goes, I don't have a netflix account, I don't plan on ever having one. I am completely saturated in terms of TV, video games and media so I don't really need another thing, especially if I have to pay for it. I tried to play with people on gold, however when I tried I could not get a match due to no one playing online, its the same as the Wii, no one plays any of the games I care about playing. If you are doing Call of Duty or Halo then fine, but I don't even like those games so that is pointless. If I could get a match on the games I play I might consider paying for it, but since people don't use every game on there... its very pointless.
