Filesystem is mostly useful for a number of cases (though perhaps not the average person), but I am glad it's there and one can access external storage or /system (read only) without root. It's pretty useful for the following conditions: 1) root users that want move around and change config files (boot animations, system wide theming, etc). Also for flashing stuff in recovery where you need to point to the file you want. 2) ROM modders/developers - looking at various files live on the device and also for low level things such as filesystem access in recovery to get yourself out of a jam. 3) app developers - I like to use sftp on my device and sshfs on my pc to directly access sqlite dbs for apps I am working on and play with the db directly without having to reinstall the app to update it. 4) Those that want apps that obey filesystem rules versus global (like for a music player, I use one that reads by directory instead of just dumping everything in by tags).
