CPU - More and faster cores = more stuff simultaneously
Memory - More and faster RAM = more stuff simultaneously
Dedicated GPU - The big one and the most impactful weakness in laptops. Graphics processing is extremely important for multi-monitor, UI rendering, and video conferencing.
Cooling - All this heat needs to go somewhere. "LOL my laptop fan is about to lift off."
We operate in a world where huge numbers of open Chrome tabs, IDE files, Docker containers, chat applications all need to run perfectly while ALSO sharing screens and live audio/video.
Why Windows?
It's free-ish*.
It's compatible with everything.
And it has real Linux built in.
WSL2
"Windows Subsystem For Linux"
Microsoft put Ubuntu Linux into Windows to finally provide a "real" command line.
WSL2 means any *nix command that works on a Mac now works on Windows.
