Browser as Operating System

A walk on a cold day brings out the minimalist in me. So I was thinking "Why not the browser as operating system." This was after a long day on my laptop writing in my HEMS content management system which runs on a server on my machine. Browser and web server, what else do I need on my machine. I know some Linux consumer version were like this, but with the Google Maps and Gmail, it may soon be a reality. I would not have posted this but the recent move of Mark Lucovsky, an engineer of Windows at Microsoft to work for Google brought this to the front again. I really doubt the he and Google are working on an operating system in the traditional meaning. More like as described above. XML, the Browser and the network are a powerful hybrid of media.
