It doesn't need a file manager like the finder but just a easy way to sharing of documents between programs and upload and download things. And its not an uncommon request among those who I set iPads up for. Its a very common thing for uni students, who buy iPads for uni only to find they can't upload their work with them, they can't download past lectures and they can't manage documents properly.
I'm guessing you love moving documents around the long way. Not all of us have the time to. Emailing 20 documents individually must be fun. Not everyone has a Mac + iCloud.
Where are the statistics that seem to show that nobody wants a browser? Apple is slow to add much wanted features so saying that "Apple would have already added it if it was requested is false" Control centre was a much requested feature for years and it took till 2013 to add it.
OK yep. Lets see, you can use iTunes to get photos on and off - Which I already said BESIDES iTunes, there is photstream which is annoying and slow, third party apps which all involve using networks and shared folders to sync things on and off.
All I want to do sometimes, is to import a large number of photos from my Macbook onto an iPad, sometimes mine and often times someone else's - I don't want to use iTunes as you're then tied down to syncing things and it gets annoying. Why can't I just drag and drop?
I wish people would stop being absolute fanbois and see that doing things Apple's way is NOT easier/the best solution in this respect.
Every single thing you just said is made completely and utterly irrelevant because of the cloud. If you don't have a mac, then you can easily use Dropbox, or a million other free cloud services.
Emailing 20 documents...? I don't know why you keep acting as if this needs a file manager, or as if a file manager would somehow make this ANY easier. Because it wouldn't. Apple could easily just give you the ability to select a few documents in Pages and hit the share button. That would be a lot easier than some sort of file manager.
Copying a lot of photos to the iPad? This is even easier, on a mac just add them in to Photostream. Done. How, exactly, would a file manager on the ipad make this any easier? I can't imagine having to use iTunes to copy photos to an ipad. There are ten thousand ways to do this, including many ways offered by Apple themselves, and iTunes would be my very last choice.
You say you "want an easy way to share documents between programs" on the ipad? Apple said 2 months ago that with iOS 8 they will be coming out with an extremely simple and powerful Extensibility framework that will vastly improve inter-app communications. It will do things like allow third party apps to add their own filters directly in to the Camera app. Extensibility, in my opinion, is a FAR easier and far more elegant solution to this problem, not some 1990's style file manager.
----------
No app on a non-jail broken iOS device is capable of the features we're discussing in this thread. Namely a fully fledged file system and a way for apps to access those files on a global OS wide scale.
Why on earth would anyone ever want this...? Perhaps I am too young, but I never did like the old folder-directory style of doing things on computers. It was very inelegant. For example, you click the "upload picture" button on a website, and it requires you to navigate and sift through your entire hard drive trying to find the folder that you dropped the photo in to. THAT is how iOS is superior, because in iOS it literally will immediately let you pick a photo from your camera roll.
A filesystem is powerful, and it's how software (even on mobile devices) views the computer, but in terms of actually doing things on a mobile device, a full fledged file system would be impractical for 99% of the users out there who just want to check Facebook and play Candy Crush. You can't blame Apple for valuing 99% of their customers requests over the 1% who want some ancient filesystem UI.
I don't mean to be rude but you're bogging this discussion down with nonsense.
People might not realise they want a file manager (or at least a vastly improved way of managing files) but I constantly hear people complain about the inability to attach multiple files to emails. The lack of a decent file management solution in iOS is the root cause of that problem.
Let me ask you this. Do you know how many thousands of people delete a text message every day and then call Apple asking why it "went away"? Or how many thousands turn on some Accessibility feature and then call in to ask how to turn it off? Can you even comprehend the damage and headaches these people would cause if they had access to the entire iOS filesystem? These are the people who don't own computers because they don't know how they work.
File systems, folders, directories, etc. genuinely confuse these people. While someone like you and me obviously know how file systems work and love computers, the "masses" don't, and they much prefer the simplicity of a mobile device to the file system of a computer. These people make up a huge number of Apple's mobile customers. You can't blame them for wanting to try and appease them and the power users with a kind of middle road approach. I think that Apple's whole Extensibility framework for inter-app communication and file sharing is gonna fix all of these problems that both of you keep bringing up. There are much better ways to solve these problems than simply throwing in a filesystem.
