Vim works out of the box (heck, even old-school vi did.) Amp seems to provide more out of the box, but also explicitly states plans a runtime and plug-in support for extensibility, so apparently it still recognizes that complete out of the box is an unattainable goal given diversity (and conflict) of user needs.
