Of course you have a right to complain as a consumer. That's what the majority of this forum does, provide a place for people to complain and voice the shortcomings of the product.
But your complaining has never been productive, only entitled and short tempered. And therefore it's been incredibly annoying. You don't seem to be happy at all with the product you're using, and seem to find more value in being upset, angry, and maintaining your "rights" rather than offering productive solutions and opening up the floor for a good back and forth and healthy conversation.
Instead, you state your POV and leave it that way, and seemingly nothing can help inform, improve, or complicate it. It's a very childish way to act.
You asked if they're every going to do a normal file system. The answer is most likely no, as it seems to be against Apple's entire philosophy of iOS. You can't really compare the size of a product in the same way. That's a physical change, whereas a change to the software is more grounded in philosophy.
If Apple wanted to add more buttons to the hardware, that would be a groundbreaking philosophical change akin to adding a file system. Is the current method bad? Yes! It's painful to have to save a pdf to iBooks and then email it out. There must be a better way. But Apple is clearly trying to steer clear of the hierarchical folder system and come up with a better method. There's definitely room for more intuitive organization, preferably handled by the phone itself, but normal folders that you're used to on a desktop won't happen.
