Within minutes of using, signed up for unlimited storage plan after comparing (and using) dozens of photo services - flickr, dropbox/carousel, onedrive, icloud, google, everpix, etc, etc.
Allows:
-Photo-driven interface
-Video. No duration limit (like flickr), so I can put baby videos oneline (walking, bitthdays, etc)
-Autoupload from iphone (unlike onedrive, current flickr, and most others)
-Leaves photostream intact (unlike carousel). And not a slave to apple.
-Desktop pc to upload the thousands of pictures on my pc.
-Ability to download from cloud (via months zips)
-Integration with other services - flickr, amazon, facebook) to import more pictures/albums
-Smart duplicate detection (very helpful since I have created duplicates of trips/baby pics), timeline creation
-Compatible with digital picture frames (nixplayer, for family/grandparents)
-Timeline of ALL my photos, viewable and downloadable from my iphone.
-Integrates all my pc, phone, digital camera, screenshots, backups, and other online services into one spot.
-Sharing and security
-Web interface (like Flickr) that is top notch (unlike amorphous icloud)
-EVERYTHING is finally safe online
