What do you like best?
Strong ECM software, with good horizontal and vertical scalability, which offers a very good performance even in large deployments with good capacities to manage different layers of file, resulting in a significant savings in storage costs. Good collaborative skills. Large connectivity options and customization posibilities.
What do you dislike?
The administrative tools may be a little poor when using a wide enterprise deployment, what's in fact the target of this product.
May be you need an 360º view with all your content and archive servers, storage systems and more... or you'll need to filter relevant data that may have sense only on your bussiness case. I know these are things that the vendor cannot buid in a standard way, but you can solve it by creating your own tools with api, webservices and other technologies.
