Amazon says Prime Photos will not have any file or upload limits. Customers can upload photos from any device, in their original file size. But Amazon’s problem is that unlike companies like Apple and Google, it has very few smartphone customers of its own, so is at the mercy of app store dynamics in terms of getting its mobile app in the hands of new users. And unlike Flickr and Facebook, it’s not considered a “social” company where photo-sharing is the norm.
It looks like a Mac app is in the works. This is an interesting turn of events for Apple. They are facing competition from Yahoo, Google, Dropbox, PictureLife, and Amazon.
