> The post gave some use cases involving hardware that can't easily run Desktop VSCode (e.g. iPads and Chromebooks). I just don't see that being much of a use case though, except in desperate circumstances where a more capable dev machine isn't available.

This is _huge_ for education. Many school districts are distributing managed chromebooks to each student because of their low cost of ownership and really all you could code on with those was replit.com. VS Code in the browser allows you to expose students to a programming environment just like what they'd use professionally.

This isn't meant for the developer with the latest 16" MacBook Pro, it's meant for people who can't necessarily install vscode on their machine. Maybe it's on a shared machine at a library and they can't install software, or maybe it's a Chromebook.
