At home: emulating old games, wifi hot spot (not needed so much these days) for hotel rooms with wired internet, and a plex server to serve videos to the kid's iPads in the car during road trips. At work: show Grafana dashboards on our 4k monitors. Currently using model 3 which doesn't like 4k so much. I'm looking forward to upgrading to the 4 in this case, see if they are more reliable. The 3's like to crash/reboot periodically and really struggle to drive the 4k display at a decent speed.
