Well, yeah, sure; I suppose it brings come comfort about the Dropbox folks to know that they store your keys out of inescapable architectural necessity, but it doesn't really add to the point. And, actually, unless they've changed the way they do things pretty radically, Dropbox needs your keys for more than web access. There was a pretty big kerfuffle some months back when someone smartly realized that Dropbox touts how it saves storage space via deduplication. But you can't effectively detect duplication in encrypted files, so Dropbox has to be making use of user keys at some point to decrypt.
