Can you symlink your files/folders in other parts of the filesystem of the SGS2 to the DropBox folder so enabling you to sync files/folders from anywhere in the device without manually copying them (as you can with the desktop versions)? I suspect that the Android OS does not allow you to do this, but I am not an Android user.

On the N9 you have this capability out of the box. But none of the three existing DropBox applications for the N9 allows you to take advantage of it, unfortunately. Perhaps they will be improved to allow that.

@erendorn: You are right that I may have been too hasty in my judgment, since the N9 is only so recently out. I guess time will tell...
