Do any computer power supplies sold in the United States have power factor 
correction?  I believe they are standard in Europe but I'm not sure about 
the US.

Also, in another newsgroup a poster argued that the Kill-a-watt meter isn't 
accurate when used with a computer due to the switching power supply.  He 
claimed that the Kill-a-watt meter needed a true sine wave for accuracy and 
that the switching power supply warped the normal AC sine wave.  I have no 
idea as to the validity of that argument but figured you would be the guy to 
ask.
