Another situation in which this can occur is if you use external storage devices, such as flash disks, external harddrives or digital cameras. If you don't plug them in in the right order, they'll end up with different device names. This is ok if you do all your mounts manually, but if you want to use fstab to remember things then this just won't work.
Disk labels provide one way of abstracting the partitions away, however they cannot be guaranteed to be unique for a system. Consider what might happen if you have a system installed using labels, with labels like ROOT, VAR, USR etc, and then you put another disk into your machine with the same labels. Which ones get mounted? This isn't such a contrived example - some linux distributions will label partitions for you, eg RedHat.
-The partition [UUID] is guaranteed to be universally unique, and will always point to the same partition. [UUID]s are supported on all (AddToMe: check this) filesystems linux supports, including swap.

.
To find out the [UUID] of an existing partition, use the blkid program that comes with e2fsprogs.
To specify a [UUID] or a label in your /etc/fstab, replace the device name (eg, /dev/sda1) with UUID=..... or LABEL=....
