In general, everything done with coroutines can be computed 
as well without it.  At the end, coroutines are a question 
of style. There is hope that for certain classes of 
problems, coroutines help to reduce complexity for the 
developer (who has learned how to use coroutines). Typical 
application areas are generators (i.e. technically speaking 
infinite loops that are suspended after each result, the 
generator example) and event driven programs suspending from 
time to time their execution. While traditionally event 
driven programs require to split up the logic into small 
functions (i have to admit to like this), coroutines 
facilitate a linear programming style.

Coroutines are certainly an interesting concept. Whether or 
not it is "being worth it" can only be estimated by the eye 
of the beholder.
