How much security do you think you'll get in that coffee shop?  I also
have a notebook computer that has a firewall running, even when on my
home network, behind a firewall.

Disabling ping provides nothing more than a false sense of security. 
Getting back to the physical example, it amounts to nothing more than
removing the house numbers from your home.  The house is still there and
can be found by other means.
