Call me crazy, but at the rates data costs are decreasing, it seems like Amazon could create this service as a loss leader and give it away for free. What does the future look like? Everyone paying $10 month to have data in the cloud? I doubt it. This doesn't mean I don't adore Dropbox and recommend it to everyone I know, because I do (and I pay for it), but it seems like the reality is that this type of service must evolve very quickly in order to stay in front of the curve.
