QNX was almost this. I believe at one point you could even run Firefox or Chrome on it. > And also for more rigorous work tasks (programming, video editing, sound editing) Somewhat amusingly, an OS like DOS (or QNX) would probably be better at video/sound editing than any "modern" OS. It took a long time for Linux to be able to do audio processing or other real-time low latency things. Even today you may have to tweak things a bit[1] depending on your use case. A video editor that has complete control over your machine would absolutely scream. A lightweight DOS with support for newer hardware (USB, PCIe, etc.) with a thin Vulkan/OpenGL and networking stack would probably be ideal for these types of apps.
