I find that, with a good IDE, the expressiveness of some typed langs matches that of dyn typed langs. You write a bit more code (the types) when using a typed lang, but you write a bit less tests (the stand-in for types dyn langs offer) and your IDE takes care of many of your type signatures.

The fast dev times, as in quick "edit -> run -> try" loops, it what I find most attractive of the dyn langs nowadays. And gradual typing might be a way to get there, although I think it is not needed (some strong typed langs have decent hot code reload).
