My Chrome install is ~600MB and 115 dirents. (Not including UserData.) It runs ~1 process per tab. Comparable in scope and complexity? That's debatable, but I tend to agree that modern browsers are pretty similar in scope to what an OS should be. (The other day my "web browser" flashed the firmware on the microcontroller for my keyboard.)

They're not even close to "being comparable in size," although I guess that says more about Windows.

Basically all code pages should be the same if some other VM has the same version of ubuntu and running the same version of spotify/slack.

And remember that as well as RAM savings, you also get 'instant loading' because there is no need to do slow SSD accesses to load hundreds of megabytes of a chromium binary to get slack running...
