- 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? :)
