Google seems convinced the cloud is the future. Do you think Google is just pushing their business model?
The cloud is a basically idiot idea. Pretending to serve you just because "your documents won't be on your PCs anymore, you can access them wherever you are and whenever you need them" is plain stupid, 'cos this wonderful thing just stops working when you loose your connection to the Internet. So the right plan is: make Internet always available, anywhere, anytime, and possibly free, and THEN move all your datas on the Internet. But beware: people is not dumb, they simply won't pay a monthly free just to keep their personal data, feelings and life on a remote server placed somewhere else.
