The Future of Dropbox
If you give Dropbox to a user that is not technical at all, they will have lots of problem figuring it out. The reason for this is that Dropbox does not have a lot of user interface exposed on the desktop. The user needs to have a basic understanding of how their operating system works [to use Dropbox]. The fact that it is so invisible and behind the scenes is why they [non-technical users] don’t know how to use it.
Some interesting upcoming features are easier sharing and automatic file viewing and transcoding.
