Me too, but if what I heard once had any validity to it, the Smithsonian once considering putting the Enterprise model into storage. I don't know.
If that's true then the toy and gift shop display was a nice compromise where people can still see and have their pictures taken with it.
Yup. From that perspective -- which is quite plausible, because the Smithsonian owns several times as many items as they have room to display -- I'm glad it's at least in the shop!
