That's probably because you don't really see the value of udev.

Looking at my 10-local.rules, I have rules that:

1. ensure that whatever wireless card I decide to plugin becomes
"wlan", instead of eth0, ath0, or wlan0.

2. Makes all of my usb media devices (flash disks, 2.5in hard disks,
3.5in HDs, and media reader) show up at persistent nodes, instead of
sdX devices where X depends on what devices are connected and the
order that they are turned on.

Neither of the above is possible with a static configuration or devfs.

Yes, there are problems from time to time (like when all of the devfs
compatibility nodes were removed!).  But I've never had a problem
debugging what udev was doing (set udev_log in udev.conf and watch
/var/log/messages).
