Android and iOS provide sandboxes for applications so you can install less trustworthy apps with smaller risk. Desktop OS's should really catch up here. Maybe not to the extreme level as iOS where there isn't even a concept of file system but at least provide a separate safe storage location for each application. Every application shouldn't have to reinvent encryption of its storage just so other apps can't read the data.
