I would not store wallet.dat in Dropbox: http://venturebeat.com/2011/06/21/dropbox-files-left-unprotected-for-four-hours-due-to-software-bug/

I would definitely call that a big "Whoops", considering people ARE using it to store things like financial data, legal forms, and more. Dropbox is GREAT for file sharing, but I would never place anything sensitive there.

I'm surprised more people aren't using wuala (wuala.com) considering it uses client-side encryption and isn't based in the US.

Im surprised people just dont use cd's.

cds nuts?
