It has helped us manage our documents in one place, it's easy to use and very customizable for your own needs as well! I don't think there are any downsides yet - but if you're looking into this software make sure that all of these features will be helpful when using them within an organization setting- because some people may not like how they work or look out side their home/office environment.
We've been able to keep track of our files easily by uploading them via dropbox directly from my computer instead of having to save copies everywhere we go (which was getting cumbersome).
