So I picked up a Kill-a-watt the other day (thanks Joe), which is a power meter that sits between the electrical outlet and any device.
I have been measuring everything on earth, a few specs from some devices I checked out:

-------------------------------------------------------------------
Atom Dual Core Desktop PC:
- Intel embedded mb D945GCLF2
- Atom 330 1.6ghz embedded CPU (8 watt)
- 1 Stick Kingston DDR2-6400 2gb 9905316-132.A01LF
- Hitachi HDP725032GLA360 320gb SATA2 low power harddrive
- DVDRW LG GCC-H23N IDE DVD Burner
- 5in1 USB Card reader
- 150 Watt no-name PSU with 60mm fan
Average power usage measured over a 4 day period was 1.22 kw per day. It uses a mere 48 watts during normal usage, and 63 watts when burning a DVD (most processors alone burn 65-95).
At $.13 per kilowatt, this PC is costing me $58 per year to run 24/7 - its GRRREAT!
-----------------------------------------------------------------------------------------------
My Asus eee 901 Atom netbook is even less @ 11 watts with screen on medium brite, this little laptop would cost me $12 per year if I ran it 24/7 - luckily I only use it half that much ;)!
My Westinghouse 22" LCD is running a cool 33 watts compared to the 300 watts of my 61 inch rear projection (old skool) HDTV, fortunately I dont watch much TV.
