Why only two plugs?

A friend of mine sent me this link. I tend to agree with the first comment on this article - Why are there only two plugs on Air Force Two? Dick Cheney is in dire need of recharging his ipod and pisses off the reporters for using the only other free plug to do it rather than let them file reports. My next question is, and this is as a member of the media, if these are real reporters, why don't they have back-up batteries??
