Do you feel that power outlets are in short supply on a plane?

If you are flying coach on most planes in the United States, you are probably right. When I fly, I always go to Seat Guru and see if there is anyway that I can get a seat that has a power outlet. 
Most of the flights that I am on in coach, I am firmly out of luck.
This article does a great job of pointing out all of the seating differences....based on seat cost. Not shocking, but it does show that you do get more than a nice seat when you pay more for your seat.
