Amazon updated it’s apps to include desktop sync with it’s android apps.

5Gb of storage is provided for free on Amazon’s Cloud Drive service, with upgrades available for one terabyte of data for $500 per year, which undercuts Dropbox.

The update also brings with it automatic uploading of photos, much like Dropbox or Apple’s Photo Stream services offer. Take a picture or screenshot on an Amazon Cloud Drive-enabled device, like your Android phone, the photo will be automatically uploaded to the cloud, accessible with any of the Cloud Drive apps, desktop or Android. You can also upload photos one at a time, and disable the auto-upload, if you wish.
