Joyent manifesto:

The influence of web applications has made its way into the user experiences of operating systems accelerating the acceptance, by users, of user experiences that can be best developed using web application development stacks (or portable runtimes such as Flash, Slingshot, etc.). This will push the client operating system to a position of irrelevance in time. Yeah, I'll need an OS to run my device, but I won't care which OS because developers are moving up the stack on the edge device just as they've moved up the stack on the server.
