For the last year or so, when I fly, I've been flying Delta. At Charlotte's airport, the primary carrier is US Airways and they have relegated pretty much everyone else (Delta, United, American, Southwest) to the A concourse. And since everything in Charlotte is connected once you're through security, I usually use the B security checkpoint since it has a line not only for the elite/preferred customers but they also have one for the TSA Precheck folks.
But for this trip, I was flying on US Air out of the E concourse and so I chose to have my security theater performed at the D/E checkpoint which also has a TSA Precheck line. My security officer was quite and efficient when he violated my rights.
As a TSA Precheck traveler, I get to keep my shoes on, my laptop stays in my bag and I don't have to put my hands in the air and get irradiated very often. If you travel much, I strongly suggest that you sign up for the Global Entry program ($100), which gets you a Known Traveler number that you enter into your air ticket purchase. This gets you a very good chance of pre-check and the above listed security "bypass" stuff.
I love this airport!
