Dropbox is more than just a place to share photos or business files (though that is also good).
We’ve tried out a few of the competitors, and we still feel that the Dropbox interface beats the others hands-down.
A little-known feature is the ability to automatically sync your photos to its cloud storage. If you’ve ever lost your phone and panicked that you didn’t backup, Dropbox will rescue you. After you’ve completed the initial setup, your phone’s photos are backed up, every time you plug in your phone, or are within WiFi range (depending on your setup).
