Using the Legend Package has one big disadvantage because it "destroys the
coordinates" in combination with using the Text[...] option.

p=Plot[{Sin[x]}, {x,-3,3}, DisplayFunction->Identity];
Show[{p,Graphics[Text["Sin", {1,1}]]}, DisplayFunction->$DisplayFunction];

plots the curve and puts the text "Sin" to the coordinates (1,1) but

p=Plot[{Sin[x]}, {x,-3,3}, DisplayFunction->Identity,
Show[{p,Graphics[Text["Sin", {1,1}]]}, DisplayFunction->$DisplayFunction];

plots the curve and puts the text anywhere else.
