Funny, we use the tablet to watch the news in the kitchen via a streaming app instead of having the TV louder in the other room. The thing is, at least in Portugal, most service providers (NOS, Vodafone, Cabovisao, Meo) have streaming applications for tablets 'n' smartphones but you can only get them if you subscribe to their full list of services (TV, phone and Internet).
I use Internet for my work, I barely watch TV save for the news, I don't use the phone 'cept for ordering pizzas and I haven't done it since forever.
Once I get my own apartament, it's just Internet only for me.
