It also allows APs to be "hidden", by not broadcasting its own SSID, but relying on devices to send out a probe to ask if it's there. Of course, it's not hidden from packet sniffers if it's talking to someone.

Not only is a "hidden" AP not really hidden at all, it makes a lot of functionality much more difficult, such as channel choosing and reconnect.
