I agree.  It's mostly a nicety.  It does also enhance the quality of
your logs though.  When you see that a user connected from "gubbins.lan"
instead of "dhcp21.lan", you have a much better idea of which computer
it came from.

I think of it as not terribly hard to do[1], and it makes life a little
bit nicer so I did it.

DHCP is still useful in this instance, to effect other settings such as
domain and dns servers.

[1] Unsafely, though.  I didn't bother doing the secure dns thing.
