Are you aware that the xbox is an appliance, like a dvd player? My original NES also "still works fine". No, it hasn't been updated at all.
Xbox 360 hasn't been updated since 2019. I'd hardly consider that supported, and you're using vastly different qualities and quantities for matter of comparison.
Apple seems to do pretty well for feature and security updates, so I'm not sure what you're talking about as a gripe. In contrast to the ~4-8 years Apple supports their devices, Microsoft only supports the major releases of their OS for a very brief period of time (usually about 2 years). It's uncommon for a laptop to be able to be easily upgraded between minor MS releases without breaking things irreparably on x86 (you'll be lucky to get driver support), and major releases are much shorter.
MS has done quite well with the Surface devices and keeping them supported, but it's by far the exception for them and they have a long history of -not- doing the right thing.
