Here on my network, I have a few fixed location computers and some
notebooks and a pile of phones and tablets.    All but the fixed location
machines get moved around and are sometimes running on other networks.   I
don't want my phone of notebooks to be static.  I want these mobile devices
to connect using DHCP to whatever network they are near.  So I need DHCP at
home.   If you have any mobile devices that you need to have DHCP.

Once you already have DHCP how much extra work is it to make the IP lease
fixed?  One or two mouse clicks.  Then you have a central place to do all
the IP assignments and there is little chance to using the same IP twice.
