What will users need from a Cloud OS?
They will need more than just web based copies of their current desktop tools. A good way to understand this is to compare a blog to a word processor. They are both content creation tools, but writing information within a blog can lead to network effects. As more people comment on your article, it gains more value. As more people cross-link to your article, it gains value and gets a higher ranking on search results. The same is not true of content locked within a doc file.
For the enterprise, an OS combined with applications become the vehicle for doing the following
- Creating content ( words, pictures, presentations, video )
- Analyzing data ( Excel )
- Communicating with colleagues ( Email, IM )
- Storing information
- Finding information
- Running domain specific applications ( Expense tracker, CRM, ERP, IDE )
