"Useful non-Apple sync app"
Double twist looks like an iTunes knockoff, and to some extent it is. I find it useful for syncing my Android with material on my macbook. And it's free, at least for the cabled version.
Not fully functional with Apple products; free version requires a USB cable.
Highly recommended for those of us with cross-platform needs. Docked a star for incomplete mac functionality and not making the wireless version free.
