Zoho Notebook
ZOHO NOTEBOOK offers some interesting features, including a whiteboard function, straightforward "add" buttons for adding text, graphics, photos, audio, video, RSS feeds and documents to your notebook. You can combine and add Notebook pages from other applications such as Zoho Writer and Zoho Sheet and then share the notebook through a very efficient versioning control. Like Google Docs, Zoho Notebook offers real-time simultaneous editing and sharing of content. You can integrate Skype into the pages for instant chat and telephony. After using the Zoho Virtual Office, I wonder if there's any compelling reason to buy dozens of computer-bound Office applications.
