For scenario 1: I guess a secondary question, if scenario 1 happens, what this means for S3 as a cloud storage solution? I know the market is not that big, but google's cost competitiveness on cloud storage has to have some effect. 2: I think the likelihood of this is low, unless Google does it to kill off dropbox. 3: I personally would probably use both, but for different reason, google's sync so I can remotely manage documents I want to use in google's apps, and dropbox for a quick and dumb file syncing for other stuff. I can see the competitiveness still working out here. 4: I agree, I'm a huge fan of dropbox, see #3 above.
