The televison in my hotel room is a typical weird hotel tv, not quite the same as a normal one, strange front end menu system. When you turn it off using the big button on the front, a message is displayed on a little LED panel to say 'OFF'. This stays until you turn it on again. My definition of off obviously isn't the same as Philips'.
Makes me think of a lot of PCs these days, their power buttons don't actually turn the power off, but mearly suggest to the machine that a shutdown has been requested. It seems then to be up to the PC to actually turn off if it wants. Of course what usually happens is that you're pressing the button because the machine has gotten itself into a state and is either too busy to field power off suggestions, or not in the mood, so it doesn't even work.
We're loosing control of the machines we're building! Of course there's always the power cable....
