I guess it's all relative. I sorta agree with you. I would rather snatch my 7 inch Nexus 7 to watch a video then do it on a smartphone. Then again, I would rather Chromecast that video to my TV than watch it on my tablet. In the end, my smartphone is sufficient for short youtube clips, but if I have time to watch a movie, I'm typically in a situation in which I have my tablet or I am already at home.
The nexus 6 intrigues me; but ultimately, any tablet will be better than a phone for this purpose.
