You have to remember that you have two types of users here. You have
the normal users - they want to connect to the access point without
problems. Hiding the SSID hurts them. Then you have the cracker.
Hiding the SSID does not hamper him, as he is capturing packets
anyway to help break the encryption. This gives him the SSID as part
of the process even if it not being broadcast. So as a security
measure, it does not add security, while at the same time, it is
making it harder for normal users.

The one exception I can see to that is if the only security is
hiding the SSID. The the person cracking the system has to find the
SSID before connecting. The normal users already have it. But they
have to tell the computer what SSID you are trying to connect to,
instead of the system seeing the SSID and connecting to it, or
giving you a choice of SSIDs to connect to.
