NetworkManager, is it important?

I have F12 running on my personal laptop (Dell D630) and my work desktop.
I think that NM is appropriate and useful on my laptop  but not my desktop.

When I use my laptop at home, I connect to my home network via WiFi,
and sometimes I used a wired connection.  I've used both wired and
wireless connections elsewhere.  So far, NM has correctly connected in
all these situations, using DHCP.

My work desktop, however, has a wired connection with a fixed IP address.
In this case, NM is not useful.  So I did (as root):

  service NetworkManager off
  chkconfig NetworkManager off

Then I modified /etc/resolv.conf and
/etc/sysconfig/network-scripts/ifcfg-eth0,
and I created /etc/sysconfig/network-scripts/route-eth0 (for a special route
we need at work), and then

  chkconfig network on
  service network start

I think that I could have also use config tools in Gnome to do the same
thing, but the above worked for me.

The usefulness of NM depends on your network setup.
