OSMC makes some good Kodi boxes under the Vero name if you don’t need proprietary streaming services. I use the jellyfin plugin to read from my JF server, works great. Supports 4k, HDR, audio passthrough, many codecs, all the good stuff.
Between that and my PS5 it covers all the bases
They let us use them for all my college math classes.
They really don’t help much at all if you don’t understand the math, and if you do understand, you don’t need the calculator most of the time.
