When I switched my desktop from Windows 10 -> Debian, I noticed the fans ran less (until video games). And I pretty much ran the same apps. 1/2 of the complaining is a lack of being able to choose/clean up that is running!

If it helps clarify, Apple have also let their OS quality go too. Years of under investment just shiny new veneer.

Linux has continues to improve and in my opinion is ready to be “the free default” OS on PC’s and standard laptops.
