Today, I plugged my computer into it. Because of certain physical constraints, it ended up plugged in behind the sofa and dragged across behind my head, resting on the back of the sofa. My computer was plugged in there, and I started playing. Here's what I got so far.

computer + terminal + med screen + safari streaming netflix:
...and I brought up netflix, pulled up my queue, selected a random season 5 Dr. Who episode. It started loading. I turned in my seat to view the electrical draw.
The kill-a-watt had fallen behind the cushion. I reached around to pull it out.
My hand nudged my mostly-empty can of seltzer.
It tipped. It fell against the mostly-full glass of vodka. Which tipped. And fell against the mostly-full can of seltzer, before falling off the end-table, spilling onto the couch (and my sleeve, and the kill-a-watt), and then falling to the floor, rolling into the corner, and turning right-side up (miraculously still containing some vodka).
Nothing killed, but my momentum in evaluating power has hit a wall.
But at least there's more vodka.
