I am pleasantly appalled at the fact that Amazon is offering unlimited storage. Furthermore I am so grateful at the amount of autonomy the user has in organizing their files and vastly different media types.
My main concern is digging through the files, especially on mobile, in order to access a specific file - a photograph, per se. One would have to switch from large list view in order to scroll through folders with long names, then switch to large tile view to actually see the details within the photos through which they are searching. All of this viewing filter adjustment just to find one file. That is my one concern with this otherwise incredible service.
