Buy a used older IPAD Mini. . I rep a few lines off the off brand Android tablets you speak of. They all tend to be a little slow, have not the best radio in them, Doesnt matter , Supersonic, RCA, Packard Bell, Lindsay, Ematic, Core Innovations and I can go on . Primarily all the same tablet spend a little more and get an IPAD nothing like them. If you wantedto go the lower end route I can sell you one brand new in a box for $40 plus shipping. Up to you Plastic Housing like you said android based. as just a remote maybe ok
Lightweight tablet suggestions
I'm new to streaming and thoroughly enjoy it. However, my old 10 inch tablet is rather heavy and cumbersome when making selections. I would be curious to know what others are using. My inclination is toward a 7-8 inch tablet with plastic housing if anyone is aware of one. I would use it only as a dedicated remote control for streaming.
