it’s similar. in a mainstream distribution with a desktop environment, updates can typically be configured to notify you or install automatically. it’s common for those updates to now also include third-party sources like flathub.
upgrades (to a next point release or major version) are different, some can be fairly straightforward–others, not so much. and those upgrades will be more frequent, as the “lifecycle” for most linux distributions is shorter than windows’ 10 years.
i have only ever had basic phones, dating back to my first nokia ~ 25 years ago. i don’t have the need or desire to have an android or iphone. one time. just once, ever–i enabled cellular data on my phone so i could look something up–the current weather forecast (in the kai weather ‘app’) because it started to look like i might get stranded out in a bad storm and i forgot to check the forecast before i left.
