Pretty much agree with everything, with maybe one exception, if you mainly (or only) want to watch videos, on speakers, something like the Tab A7 has better speakers and a better aspect ratio (with a good screen) for less money, but not much less money (around $100 less excluding sales), and you give up a lot of power (A8X power vs A12 power) for anything else and a it won't age nearly as well (but again for just watching video, that is not really relevant).
