For the holidays, I upgraded my TV to a fancy 4k Sony Bravia with Android TV. It was billed as DirecTV-ready. No box needed, fewer wires. I would go into detail, but typing is hard. Long story short, it sucks. Crazy slow, terrible UX. Changing the channel took 10 seconds. Fast-forward through recordings was unresponsive and skittish. If you paused a show and then god forbid pressed the wrong button on the remote, you would lose the buffer.
I reverted back to the box. Lame deal guys. Not good.
