To clarify my point, this will be just one of the approaches in the future. I see also a lot of small "clouds" on personal devices that have trusted pairs they automatically sync with. You walk in your office, and your phone/pda pulls down your days tasks from your desktop/laptop wirelessly and update everything. Maybe that data lives in a cloud, but it could be local to the company, it could be just that desktop, or it could be in a giant data warehouse.
