I use mine as a home assistant dashboard.

Use it as an e-reader for Calibre library?

• Convert it to a kitchen recipe display device and retrieve recipes off of your server.
• Home monitoring panel
• Video/Photo frame
• e-reader

Previously I used it as a home assistant panel, but everything is so automated no one ever touched it (except the kids, annoying the ever loving crap out of mom).

Now its magicmirror as a calendar display

Mine was so slow it could barely run a website anymore

But monitoring websites - maybe on LAN - could be useful

Or home automation

Media controls?

There was a point where I just had the browser opened to a monitoring dashboard.

I don’t have an iPad mini so I can’t help you
