Puter: A real, fully-featured operating system in the browser (blog.puter.com)

Interesting, maybe even amazing concept.

Question I have is Why? What are the use cases or problems this could solve?

This looks more like google drive with a windowed MDI interface.

Calling it an OS is very misleading.

This looks like a really fun project.

I fail to see the right usecase right now, I have never seen the need to store more than a few hundred GB of data on a personal computer or to use a lot of computing resources.

Serverless web hosting with one click looks really cool though, but again, I can only see its usefulness in a few niche cases.

Looks interesting. Reminds me of the web-based desktops that started popping up in the early 2000s.
