Sure, but taking your video editor example, what advantages does an in-browser app provide over a native application like DaVinci Resolve, other than portability and not needing to install the application, in exchange for reduced performance, a clunkier interface, and reduced integration with the rest of the desktop platform?

It's the issue of friction. Also, good webapps are often _better_ than native apps, as they can support tabs.

Because it relied on Java and SWING, which were a disaster for desktop apps.
