It is one of the nicest things to be able to work remotely. Almost all my jobs have allowed this. My current job allows it on a limited basis as well. It's even more attractive an option now that I have a nice desk chair at home, for which I currently long, because I'm currently typing up this post from a 2nd grader mini-chair while I wait for my lovely wife, April.
Remote working goodness is just a few shell commands away via Cisco VPN in Linux!
