	- one value per file, no char or block nodes
	- devices can export many different files depending on their
	  needs (no ioctl crud needed.)
	- you can use a script or libsysfs a web browser, or anything
	  else that reads directory trees and files to access the device
	  info.
	- you can have as many devices as you want in the system, no
	  limitations on minor numbers, or anything else.
	- no unsolvable kernel race and locking issues
	- no horribly formatted code from a developer who is no longer
	  maintaining it.

Shall I go on?  :)
