The Death of Files by Dustin Curtis
The iPhone OS completely removes the concept of a “file.” It promotes apps to being the primary level of user interaction, and it stores related things inside databases that are content-specific. When you pick up your iPhone and want to view photos, you open the Photos app, which connects to the photos database and shows you all of your photos. When you want to listen to music, you open the iPod app, which connects to the music database. Everything on the iPhone is task-centric, not file-centric. The “file” part of completing tasks is completely insulated from the user.
This is a new model for organizing things on computers, but it actually much more closely emulates the way people do things in the real world. When you want to eat, you go to the refrigerator. When you want to listen to music, you go to your stereo system. Completing these actions just requires knowing the locations of the things you want to use. If you want to look at photos in the real world, everything you might want to accomplish is in a single place: in the album on the bookshelf. The photos themselves are even inside the album.
