IPad Air, just bought one a few months ago, and like it a lot. Might be bigger than you're thinking, at almost 11".
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.
