I'll speak up.

I have a Logitech USB mouse that I use on my main machine. I have no
other pointing devices, but this mouse does happen to have extra
buttons that don't work by default except when configuring evdev to
use the *exact* USB device it is assigned to in /dev; I can't use the
/dev/mouse thingy or whatever for it.

If I unplug this mouse to go use it on my laptop, and then come back
to my desktop and plug it in, it fails to work at all because I can't
use the /dev/mouse device and the USB device number assignment
changes, even if I plug it into the exact same port. So input
hotplugging is perfect for me, and I didn't have to tweak a single
file to get it to work (other than remove crud from my xorg.conf which
is now much more manageable).
