I find having the full OS is useful, and this KDE environment proves great https://plasma-bigscreen.org/

Sounds like a Librem 5. Am currently typing from one.

PineTime

A GUI option in the Settings app to limit charging to 80%, extending the life of the device.

I walk through some neighbourhoods with many high-risk apartments, and there is so much interference from all the Wi-Fi routers, Bluetooth devices, and other wireless devices using 2.4 GHz, that even the best wireless headphones skip & stutter playback.

It also takes so much longer to switch wireless headphones to a different device, especially when they all compete to connect to the headphones.

Let me make the decision when to use wireless, don’t make it for me. A DAC USB-C dongle is dumb.
