By "green screen" he means something like a Network Computer: basically, all the grunt work isn't done on the device but on a remote server (aka "the Cloud"). A ChromeOS device doesn't do a lot of local work; thus why it relies on an Internet connection.
IOW, you don't expect a device that depends on an Internet connection for even basic operation to be a status symbol.
