My number one wanted feature on the iPad

As should be obvious by now, I love my iPad, and bring it with me most everywhere I go. I use it for work and play, planning and doodling in equal amounts. It has more or less supplanted my netbook as my default unit for web browsing, emailand many other things.
 
Along with my android phone, I’ve got internet access most anywhere I go, and am very happy about that fact, too. There is one feature from my android phone that I’d like to see however, which is only currently available on iOS devices when they’ve been jailbroken; a unified file management system.
 
On any and all android devices, you can access the file system, and any files on it, directly from the unit, allowing you to modify them at will, and opening them in other programs.
 
Sure, there are apps that sort of do what I want, but they don’t do it particularly well, nor particularly elegantly. moreover, i think it’s something that should be handled, not by some app, but natively, in the OS.
 
Like my wishes for what used to be the rotation lock button, I understand, and to some extent accept that this might not be forthcoming for some time, though I honestly think it would be a mistake on Apple’s part not to implement it soon.
