In a forum I read:
EyeOs is a virtual desktop system entirely web-based and open-source. It's written in Ajax and PHP. Applications available include simple word processing, calendars, games and more. all you need is a local web server with PHP (e.g. XAMPP).


I don't really see the utility of creating new desktop for an OS. I surfed the EyeOs site and I can't find any info about the use or the utility of this application. Every OS has a desktop, so why a new one? The only phrase about EyeOS is in the introduction of the users manual :
You're about to discover a new work and organization method: A completely free (open sourced) desktop system running from your browser.


Yes, it is PHP/Ajax based and then?
