Inexpensive tablet well suited as a control point for my streamers, including Sony

I must be stuck in the 20th century. Despite endless searching, I have been unable to find a tablet to use as a control point for a Sony HAP Z1ES and Roon. It doesn't have to be laden with bells and whistles, knobs, switches, meters, dials, buttons and gewgaws. It doesn't have to play through built-in speaker-like devices. It just needs to have a touch screen and a good display for album art and liner notes. It needs only enough muscle to do this without elaborate set up, constant pointless upgrades or impenetrable error messages. 
Any help will prompt me to write the Pope, suggesting your elevation to the daily calendar.
