I've tried to come up with which use-cases make sense for C#'s dynamic as well..
Where I mostly could figure that it would really help is with COM interop. Working with something like MS Office is fairly painful in C#3, since you have to pass the "Missing" argument to each of the 20-30 arguments that every method can take, and cast the result of every method.. The named arguments feature would also be useful there.
I've been fortunate enough to avoid having to interop with COM that directly recently, so haven't had to find out whether or not it makes a difference.
