It is often a non-issue for "appliance operators" so to speak. Most of the mundanes use tech on the toaster or coin vendor interaction level. What code either box "runs on" is of zero thought as it makes zero change.Other than a quarter change for your 2 dollar bills if the pop is $1.75 My phone is M$ based. It would be VERY desirable to replace the phone's firmware etc with Linux. As then every button/Bell/blinkenlight could work to MY settings!

My shortlist:

Network gear.

3 computers.

Cheap music player.

Pending is theSlimp3 "Squeezebox" music
