Though I like the idea of Chromecast, I'd rather carry a slightly bigger box and have more variety and privacy. I still may get one, though.

That is fine for your laptop, but not for a phone.
Also, I've yet to find WiDi working reliably enough to use it on a permanent basis. And what makes you think that Google wants to know what you watch on Chromecast? Do you have something to back that up?
