Yup, we've been using Balsamiq, it's fantastic for a lot of things but there are times when a higher-fidelity tool is needed.

On top of this, we are also creating a standardized look and toolset for all of our apps - something sort of like Bootstrap - so there are many situations where it would be great to be able to just assemble the UI pieces that we've already defined and say 'what do you think of this?' or even run through some informal usabiltiy testing.

Side note: I think Balsamiq is the main reason I was so disappointed in Axure. Balsamiq is so efficient and so good at what it does, and Axure... well, you kind of wonder if anyone at Axure actually uses Axure.
