I can't think of any good reason why you can't access your online cloud from your PC when you log into your Playstaion account. Something like this should be a no brainer. You should be able to access your Online storage not only from your PC browser but your mobile devices as well seeing that Playstation have apps for both Android and iOS. This should be a no brainer. Microsoft let's you access your online storage for pics, music, gave save date, etc... and it's fully intergrated with OneDrive. Please forgive me, but this idea isn't "genius" as much as it is "practical".
Being able to upload/download between your Online Storage and your PC or mobile device should've been standard operating procedure.
