Well, it has been a while since I last made a post and since I like talking about new technologies whose future can only be speculated I felt like bringing this up.

Thing is that Mozilla has this nice idea of getting into the OS bandwagon the same way Google did, but they aim for mobile devices, which is at least in my opinion a way better choice for such an OS.
But anyway the project aims to make not necessarily a browser OS, more of a browser development environment where apps could be created using existing open technologies like HTML5 which is at least in my opinion really awesome.

So yeah, can't wait to see how this project evolves.
Also here is the projects' page if you feel like reading more about it.
