I found it useful recently, when I needed zip functions for Trees - this way I didn't have to define functions for 3 trees, 4 trees, and so on.
Note also that:
repeat f `zwApply` xs = map f xs
When cooking up my own collection-y things (including splittable supplies, for example), I generally provide fmap and an equivalent of zwApply (a generic repeat is not quite so simple or useful). It's a nice little idiom, and a recommend it highly.
