No doubt, sniffing is much easier on a hub than a switch. My point is
simply that it takes less effort to observe all the traffic on the
outside leg of a network if a hub is used to connect the nodes, than if
a switch is used.

Unmanaged switches are available and cheap. For instance, an 8 port HP
unmanaged switch can be bought (J4097B) for $133 USD from their website.

Finally, while it is not likely to be an issue on the outside leg of
most networks, throughput will usually be much higher on a switched
network than on a hubbed network...
