My usage falls into three categories:
- Netflix (a lot) - Tab Casting (occasionally) - Youtube (very seldom)
I suspect that AppleTV would work better for everything except for the tab casting for me. Even with the current limitations, I don't know of another settop box that does that as effectively as the Chromecast.
Having said that, I have still been mostly disappointed with the device so far, as tab-casting has been basically the only free solution to local streaming so far. I am optimistic that this will change soon if the SDK is really open, though.
