I don't even know where to begin after reading that.. The reason for making Wii very under powered is so it can be left on in sleep mode 24 hours a day for freaking net updates??!! I haven't heard something so stupid in a long time. Have Nintendo engineers not heard of power saving? (dropping the speed and so power of components when the system isn't being used for gaming)..
Well, they've implemented a power saving mode in Wii. According to their jp-Website it draws less than a miniature light-bulb in that mode.
