All that has been done here, is replacing the OS with the browser. That is actually what is happening. Now I am intrigued: an OS that is its own browser. Not eyeOS and the like: I mean the window manager is the browser. You browse a VFS which is mounted, locally or remotely; the browser doesn't see a difference. XUL is the default UI language. The browser handles threading, even. You have no desktop but you have a homepage. Exit the browser, power down. Am I talking about something that exists? Stripped-down single-app systems like kiosks don't count... or should they count?
