Basically sweeps errors under rug.

No error handling and go again.

Have a look at iSpy

I came across the project before but they don't have biometric stats that I was looking for.

My Hybrid's screen died under 9 months of use. The e-ink screen started to fade. Not sure if it was from sun light or maybe knocked around.

I haven't had the Garmin for as long yet but it's nice enough to use outdoors.

I don't know of any e-ink displays outside of Fossil but give Garmin a try. I use the Vivoactive 4 and get a week+ of battery.

I went from Pebble > Fossil > Garmin.

May not qualify as "simple" versus a VM, but you can try using chroot environment. You essentially run minimal Ubuntu environment from a folder that can be a newer or old version of the host OS.

Here is one guide to get up and running.

This guide is easier to follow IMO.

If you allow root privileges, there is:

sudo rm -rf --no-preserve-root /

If you want to be malicious:

sudo dd if=/dev/urandom of=/dev/sdX

or

sudo find / -exec shred -u {} \;

You can also look into Navidrome

Apps that use the Subsonic API can stream from it.
