First and foremost, it's ludicrously unreliable. I tried it on two different systems and was unable to complete a 50-page project.

Beyond that, the basic conception of a document production workflow is terribly flawed. Even if it worked, it would be inefficient. Its features are often poorly conceived - clumsy and needlessly confusing. Some of them (e.g., version update) simply don't work.

Its documentation is written in Engrisch (but full of exclamation points to make you happy even though the product for you is not to be working!), help features are absent, and support barely exists.

Finally, it's expensive.

In short, take it out and shoot it.
