We love to praise linux constantly and tell everyone to change to it (they should) but what are your biggest annoyances ?
Mine would be, installing software (made even more complex by flatpaks being added, among the 5 other ways there already were to install software) and probably wifi power management issues.
https://porteus-kiosk.org/ looks like a distro that makes it easy.
I’ve messed with Porteus before, it’s still janky, and locked down, not fully open source. Better than nothing, but still not as easy as Windows.
