I tried the OS "YouOS" which starts with a web browser

I feel like logging in and operating. Since I can create an account for free, I tried it immediately. Welcome to YouOS.

I logged in and started the mail software

Various applications can be launched from the button on the upper left

IRC chat is also possible

It is also possible to hit a shell

Saved files are of course saved on the remote. The sticky note on the right is visible.
