unless you're using older, more limited hardware in which case you kinda need the OS to not use a shitton of resources so you can actually run programs that do.

i never upgraded the RAM in my thinkpad X230T past 4 GB because on linux with TDE i genuinely don't need to. i can open multiple instances of waterfox and vivaldi and do a digital painting in krita all at the same time without having to worry about OOM at all.

the difference is night and day compared to trying to do the same on windows or even linux with a heavyweight DE, under which i can maybe get a few tabs open in a single browser before it just freezes.
