Actually it is more than a convenience if you only intend to communicate to
one
peer address; it improves performance because the kernel will not have to
"connect/unconnect" the socket everytime it needs to send a datagram.
Granted
the performance is nil for most UDP applications which don't use large
bandwidth but for those that do (and TCP still doesn't make sense for some
reason) then it is the preferred way.
Connecting a server UDP socket also insures that the only packets passed to
your
socket are from the address you expect which is cool if ya ask me.
