Because sometimes just the answers in the DNS are what is
required. Also most ISP's offer secondary service for their
customers so in general there is no reason not the have a off
site secondary. There are also sites that provide secondary
services for free.

Well you are forgetting the case where the nameserver daemon
has fallen over but the web server hasn't. Having a secondary
allows you to continue offering services. There are plenty of
advantages to having a secondary that are not necessarily obvious
at first glance.

Once a secondary is configured it will automatically transfer
the zone contents when ever you update the master provided you
remember to update the serial number for the zone.
This assumes you don't have a syntax error in the zone file
because named will refuse to allow outgoing zone transfers if
it detects a error. Check your logs after each update (even
if you don't have a secondary).
