Google Docs is not getting market either (less than 1%), I think both platforms are a bit ahead of their time. People like M$ Office and Open Office, and are not so used to the idea of collaboration.
In many companies, there isn't information management (ECM, ERP, CRM etc.) and only a shared files server can be found.
The transition to newer technologies is always smooth and soft, unless the technology proves itself to be close to a miracle.
The success is coming on projects like Nuxeo, Alfresco or KnowledgeTree, which are open source and easy to install and use. You can install Nuxeo on your server and use it at a much lower cost than other ECM products (Documentum, FileNet, Oracle UCM, OpenText). And you don't have to be dependent on the cloud like with Zoho or Google Docs.
