re: Chromecast is great, but as I'm about to drop Dish for YouTubeTV, I want a remote

You want an Android TV. Specifically the Mi Box. It has a remote to work like a streaming box, while also having Chromecast capabilities (for whenever you just want to cast from your phone). I bought it with the intention of testing it and returning it, but I kept it. The box does have its issues out of the box (frame rate issues), but they are fixed through the settings menu.
