Andreas Kling has said that one of his inspirations for SerenityOS was the Windows 2000 UI (https://corecursive.com/serenity-os-with-andreas-kling/). I found his general goal for SerenityOS ("Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix.") to be strangely validating ('Wait... So it's not just me?!'). And so of course I decided to try out the KDE desktop, which I had always kinda dismissed as being a bit too much of a niche within a niche. And it's great. It really is wonderful to use an OS that is designed from the ground up for serious technical users. And the ubiquity of web apps nowadays makes Linux a far more practical choice than it was back in the day.
