I think it's important to realize that there is a difference between Dropbox, sugarsync etc and companies such as SpiderOak.
Dropbox and sugarsync both (as examples) are primarily SYNC and SHARE services that also offer backup. While SpiderOak for example is a secure backup service that also feature sync and sharing capabilities.
I can't help but not care about this. Sure it's a fun finding, but WHY is baldness considered something that is so badly in need of a 'cure'?
Of course I do understand it from a purely capitalistic viewpoint in that a 'cure' would no doubt be worth a ton of money but seriously. What's so bad about baldness?
S3 is a great service don't get me wrong. But for relatively low transaction data like backup and sync not only is the pricing high but Dropbox also have a vested interest that as they grow they do not depend on a 3rd party for what is no doubt the largest single cost of providing their service.
Not only is it not a surprise but I think Amazon.com are also well aware that Dropbox is likely developing their own storage back-end to move away from S3.
Having played my fair share of COD, MW2 and Black Ops I would unfortunately say that the 'Make a friend outside of the US' vs. 'Screw you towel-head' ratio in general does NOT provide a base for improved foreign relations or 'bridge building'.
