My very favorite thing about static DHCP are devices that require an unchanging IP address (network printers, Network Attached Storage devices, etc.), but can only be changed through a web interface.  These devices can be a nightmare to get going on a new network if you forgot to change their static IP addresses before pulling them off the old network.  You're left with a catch-22, because you can't use the device on the new network, because the device is on a different subnet, but the only way to change the device's IP address is by getting into the web interface, which you can't get to because the device is sitting on a different subnet.  You end up having to create a temporary mini network just to plug the device into to change its IP settings.  And if you don't know what the device's IP settings are, you're in even more trouble.

But if you use static DHCP, you get every single benefit of a static IP address, but when you move the device to a new network, it simply picks up a new IP address on its own.  This is also great for when, like me, you have to change your network to a new subnet and static DHCP kept me from having to move from device to device, setting up new IP addresses on them.  Everything just picked up new static addresses on their own and immediately worked on the new network.
