I voted other since I use engineering pads (granted a special kind of graph paper, but with the grid on the back side and the green color it's different)
Don't forget about the National Museum of the United States Air Force at Wright-Patterson Air Force Base. There is also the Enterprise that is already in the Smithsonian that will likely be replaced by Discovery. http://en.wikipedia.org/wiki/Space_Shuttle_Enterprise#Museum_exhibit So there are really 4 choices.
EmagGeek writes "Matthey Meeds, a real-estate agent, was so irritated about having to pay the monthly rental fee that on Tuesday he filed an antitrust suit against Time Warner Cable and its 84 percent owner, Time Warner Inc. The suit alleges that, by linking the provision of premium cable services to rental of the cable box, the companies have established illegal tying arrangements. 'Time Warner's improper tying and bundling harms competition,' Meeds' lawsuit states. 'Since the class can only rent the cable box directly from Time Warner, manufacturers of cable boxes are foreclosed from renting and/or selling cable boxes directly to members of the class at a lower cost.' I pay Comcast over $25/mo for my two DVRs. I'd love to just be able to buy them or build my own. I can't wait to see how this unfolds."
