I think this recent article by Rene highlights exactly *why* some sort of native first party file chooser is needed if iOS devices are going to move beyond the 'consumption device' label and be useful for 'real work'. Note, this isn't the same as a file system, which I don't think most people except for those who care about root access care about. Two completely different things.
And just to throw in a couple pre-emptive strikes:
1. No Sean, I'm not just name dropping Rene Ritchie's name here, I share the same frustrations as him, and it's not just Android fanboys who have a legitimate use for native document management (
NOT A FILE SYSTEM - there is a difference!).
2. I know that third party options exist. I'm currently using those third party options you're probably about to refer to. However, those third party options are a poor band-aid and an inferior solution to a native first party option.
