It's easy for users who are new at this system to use it because there are so many features available. There isn't anything I dislike about Aero Docs except perhaps if you didn't have enough storage space or wanted more than one copy stored with different permissions. The best feature we get from Aero Document is the ability to easily store multiple versions without having to manually upload each version again just when an update occurs! We also had problems uploading some files during peak hours (in Australia) but they got fixed eventually after contacting support team.
