Interesting.  According to PowerTop, my Toshiba laptop (pre sandy-bridge Core i7, running Ubuntu 12.04 64-bit) idles at 9.5 watts, assuming dim display and deactivated WiFi) and only jumps up to 15 watts when in active use.  Granted, it gets into the 20s if I open something that hammers on the CPU/GPU.  Not as pretty as a macbook, but I have more than enough money left over to wipe my tears of anguish with 100-dollar bills and still have spent less money than I would for a macbook.

This makes me wonder: Is PowerTop inaccurate compared to a real physical measurement tool?
