My 16:10 2560x1600 res Kindle Fire HDX 8.9" with the Snapdrqgon 800 handls every format I toss at in in 1080p and under. Might not handle HEVC and 4k to well but my laptop using an i7 7700hq can handle that if I even had any 4k or hevc content t begin with. Tablet is perfect if I want to read something compared to trying to read a book on my large 15.6" laptop. Also works well if I don't have much room and want to watch a quick video or 2. The tablet also lasts much longer than the laptop as well if I need to conserve battery life on the laptop. So for me Tablets have a place and 16:10 is the best resolution for a media device I have personally run into as it works quite well for most media formats whither it be 4:3 or 16:9 or something in between. Even books are decent in 16:9 since you normally get both wider and taller resolutions compared to 16:9 and 4:3 format so more words fit on screen then either at the same sharpness.
