I don't understand this obsession with outlet strips and extension cords. The user must be assumed to be completly ignorant. If it's possible to plug something in, it shall be safe to do so. You can't expect the user to know that there is a limit to how much current can be taken from a outlet strip, let alone calculate the connected load.

(Home made extension cords often pose a significant risk of fire and/or electrocution, but if you are stupid enough to mess around with something you don't understand you deserve a Darwin Award.)

I don't see any problem with daisy chaining outlet strips. Try to find a computer connected directly to a wall socket: I doubt there are more than a dozen in the whole world [Linked Image] Outlet strips are almost always used. Adding more wall receptacles won't change that: They'll just sit there unused, with a outlet strip on the floor below...
