On my Android tablet and iPhone the stores will display an an item as installed on that specific device if browsing the app stores through the device itself which I am sure you all know.
Will Sony ever be offering something similar as it's quite irritating trying to remember if I have downloaded and installed something already. The current stores a re a lot better and show clearly if something has already been purchased but not as to whether an item as been downloaded or installed.
Any news? Cheers!
