Letting one apply them with less extra characters:

add x y = x + y
map (add 2) [1..5]

instead of
add (x,y) = x + y
let add2 y = add(2,y) in map add2 [1..5] end

(The last might not technically be partial application, but it serves 
the same purpose without using currying.)

I believe it makes code shorter and more readable, but I do not believe 
it gives more power.
