It may be time to explain the "So What?" test of writing again.

You should ask yourself that question any time you write an article. (Or give a talk, teach a lesson...) If you gave enough information, that should sound like a stupid question. But if it sounds like something that might reasonably be asked, you forgot to communicate something important. In this case, the big missing piece of data is what they will be using instead of dropbox.

Because without that critical piece of data, this entire article can be summed up as "Dropbox sucks."
