On the backend Zepto can get away with not having to standardize different browser implementations of and bugs with things like events, DOM manipulation and selectors since its only targeting a small subset of modern platforms. It probably also gets rid of a few utilities. Whats left are what (at least I use) about 90% of the time: querying, manipulation and ajax.
