I switched my mum to Unix(-like).

Her router is running Linux. I can tell because of the speed of the WLAN alone.

Her STB runs Linux, specifically Android TV (Nvidia Shield TV). Thanks for adding the fantastic ads in the newest Android TV, Google! /s

Her vacuum cleaner runs Linux, I know because I slapped Valetudo on it.

Her NAS runs Linux (DSM), Synology.

Her printer runs Linux (Brother).

Her Raspberry Pi with Home Assistant runs Linux (DietPi).

Her tablet runs macOS variant, iPadOS.

Her smartphone runs macOS variant, iOS.

Her smartwatch will run macOS variant, watchOS.

OK, fair enough. Her laptop! Her laptop still runs Win... wait a sec, she hasn't had a laptop for more than a decade. She's been using that super expensive hardware keyboard for iPad. My mum never even used Windows 10 or 11. Her laptop came with Windows Vista back in the days, it was terribly sluggish.

I don't know which year it is, but it isn't the year of the Windows OS.

And yes, I am super happy with Microsoft using thumb screws like these. Squeeze them tight. The more computers will slip through your fingers, grand moff Nadella.
