Arash good security is about mitigating theoretical risks before they become actual.
I am most disappointed in Dropbox because you had made statements like all our data is AES encrypted and our staff do not have access to your data. These are clearly incomplete for the former and are plainly not true for the latter. They are misleading and un-ethical in that they have assisted you in gaining you all these customers. As stated above you should clearly stop using security as selling point and only state you provide security in transit (https) or actually put in place technical measures to make those statements true.
Personally I will no longer be recommending Dropbox and will instead recommend your competitors including changing my answers on Quora: http://www.quora.com/Dropbox?q=dropbox
