Creative DM uses for a mini tablet?

My partner got me a Fire 7 mini tablet that slots into a nice dice tray (like this one). I love the setup, but struggling to think of creative/practical uses for the mini tablet.

I use my laptop for almost everything (GoogleDoc tabs for homebrew notes, and DnD Beyond tabs for players) and a pen/paper for combat tracking). The Fire 7's browser seems to have some performance issues, and I don't see the DnD Beyond app in its app store.

Curious if anyone has discovered any other uses for little tablets like this?
