Filesystems are on their way out.
They'll never go away fully...after all, its how any system (including iOS) is run
The loss of the file system is a disaster for the average user.
File systems are not on the way out. They are better for any user than any alternative so far.
They're being hidden however, made unnecessary for all but the people designing things. Your average consumer doesn't need them, and doesn't understand them.
Rubbish.
Look at lion/mountain lion, and even look at windows 8. Both apple and Microsoft realize that's the way things are moving.
Huh? Lion is a *disaster* usability wise. Really, the file system changes in Lion are as popular as syphilis, and have very signifcantly increased the pain in the ass that is moving the vast majority of novice users from Windows to OSX. If Apple weren't forcing Lion adoption with lack of hardware drivers, destroying MobileMe and shipping all new Macs with it then it would have failed totally due to it's file system changes. Windows 8 has a complete and full file system, even in Metro.
this is already possible to an extent, and will become moreso, but it isn't being done in the traditional way (not wit ha "file system").
The reality is that iOS already has file systems. Dozens of file systems. All of which are useless for some things and have an inconsistent UI from app to app. And you really think this is better? That every app might react differently when presenting you with a file list - swiping might send the file somewhere else, or delete it, or send it to everyone in your address book, and there is no consistency to this whatsoever.
You really think that's better than a file system? Let's just look at the epic fail that is not being able to attach a photo to a pre-written mail in iOS. That's better for novice users?
Really??? How many times do we see new iOS users come on to this board and ask because they think they're being stupid?
Users want to move things between apps, but they don't want to figure out where the files are stored and move them themselves.
Nope, this is nonsense. There's actually not much reason to move things between apps at all. What users want to do is precisely move things themselves. That's pretty much the entire purpose of computing. Users want to send their pictures to people. Or share them with the world. And they will pick thousands of different ways to do it and iOS is really failing to keep track with them.
This is the point of share sheets in ios apps (and why they're being brought to ML). An app tells the system what types of files it can take. Then, whenever you have a file open you want somewhere else, you hit the share sheet button, choose what app you want it in, and boom, it's there. No saving, finding the file, opening the other app, dragging, and droppin. No opening the new app, hitting open, and navigating through the file system to the file you want
Unless the app developer hasn't thought of the other app it might want to pass it over to. Or just hasn't updated it for a year. Then you're completely screwed.
It allows all the same things, but it is a whole lot easier. I don't know why everyone is complaining about it.
Does it allow all the same things? Okay then: use your share sheet solution to...
Upload a photograph you've taken yourself to a web forum where Apple doesn't like the content enough to allow an app (say, because it features content too rude for a Victorian era sexual morality).
Copy an answer phone message from the iPhone to your new, non-Apple phone if you've decided you don't like iOS any more (I had this happen to a girl I knew who rang me in floods of tears as her iPhone had a broken screen, she could only afford to replace it with an Android handset, and she had an answer phone message that was the last recording she had of her recently deceased mother. And what was the answer? Apple's "better" way is that you should lose that, unless you're able to find someone techy like me to jailbreak the device and get file system access to it).

I suggest he try android because it has the features that are important to him.
Why buy a phone that lacks the features you want then complain about it?
The alternatives might also lack features that are important to him.
There's also the minor matter that getting data that's imporant to him off his iOS device and on to another platform is made much harder by the lack of a file system...
