The ability to provide secure drop boxes for others to send you file -alone- is worth it. Thats a must have for everybody who needs to receive files with personal data from some to time, i.e lawyers and consultants.

I hope they add some customization to the drop boxes, right now you can add a description. It should be easy to change other aspects of that page with some meta tags in the descriptions, ie: @title:Company Name @color:blue. That would not compromise security either.
