And I use one as a race car telemetry system using a 9-dof sensor and a GPS module (with brake, throttle, and steering inputs to come).
For most of these projects, they're complete overkill in terms of hardware, but with integrated wifi and bluetooth, and a host of GPIO pins, they make developing projects like this dead simple. And at $35, the amount of time they save is well worth it over bare metal hardware.
One is running our sprinklers with OpenSprinklerPi https://opensprinkler.com/product/opensprinkler-pi/
One is running VolumeIO to splay music on the speakers in our house as a Spotify Connect device https://volumio.org/
One controls our whole house humidifier via a relay and a combination of weather and thermostat information.
One has been turned into a precision/TSD/regularity rally computer for my vintage car. https://en.wikipedia.org/wiki/Regularity_rally
One runs my 3D printer using OctoPrint https://octoprint.org/download/
