On the other side...
I wish that I had known about EHell several years ago when I had a job that required a once a month all-nighter for system cleanups, upgrades, reboots, etc. I spent ssssoooo much time resting on my gluteous maximus (SP?) waiting for someone else to finish their work so that I could do stuff that required my being the only user on that part of the network! And don't get me started on the three times I lived in the computer room for an entire weekend! EHell would have kept me awake and busy!
