TiVo Roamio, basic antenna. Question.

Looking at the basic model as a possible cord-cutting alternative and instead relying on OTA network shows (95% of what I watch anyway) and paying for the few others via Amazon or Netflix. I can no longer justify paying $1500/yr to comcast in Chicago for TV (not including cable internet).

Question:

  • Does the Cast functionality work with any Cast enabled app? would it stream Google Play content, for example?
  • Is the monthly service fee required and what does that get you?

The "one box to rule them all" idea is extremely appealing to me, for the simplicity of it and for others at home to be able to use.
