I have an Nvidia Shield and like the interface but not the price. I don’t mind putting it on my main 4K movie system, but would like something less expensive for 1080 systems for sports and news. I’ve tried a couple of the cheaper mini-pizza-box Android TV units and don’t like the tablet-like interface that you (practically) have to have a keyboard and mouse for to navigate the Play Store.
Other than that, I want a usb port in case I want to add the same aftermarket remote to all of them.
I tried the FireTV but only can use the Fire Store then, and Tivo stick only works with Tivo (centric) remote.
