So, I was expecting a slight increase in my utility bill with the arrival of my dual 2.3ghz PM. I had expected it to be around $20 from another posting I read here. But I was suprised to see it spike $200 the first month the PM arrived. I think its highly unlikely that this is attributable to the PM. More than likely some other factor is the main culprit, but I just wanted to check if anyone else had encountered ludicrous increases in electric bill with the purchase of the latest PMs. Note: Yes, the time of year is factored in. This is $200 above the average summer bill. -- J.
