I can't agree with that statement. Plan9 was interesting, though it was completely based on ``everything is a file'' abstraction and had no decent solution for dealing with graphics, sound, video/multimedia, input and so on. All this ``mapping bitmaps directly to and fro the framebuffer'' and ``just create a device file for keyboard input [1]'' sounds cool til you meet some real world need. I also think that old Smalltalk and Lisp systems (e.g. Xerox PARC) had a design much more suitable for the real world applications than this ``everything is a file'' idea.
